What is a triangle with two equal sides?

The altitude drawn on the base of an isosceles triangle helps in finding the area of the triangle, which is half the product of the altitude and the base. If all three sides and angles of a triangle are equal, it is called an equilateral triangle. Thus, an equilateral triangle is also an isosceles triangle. It is also called an equiangular triangle.

How do you change a fraction to a percent?

Simplify the fractionPercent literally means "per hundred," so the fraction has to be rewritten to express the same ratio out of 100. For an example, take the fraction 4/6. Because it has a common factor of 2, it simplifies to 2/3. Convert the fractionThe denominator, or the bottom number, has to be 100. Divide 100 by 3 to yield 3.33. Multiply both parts of the fraction by this number. Done correctly, this should yield a result of 66.6/100.Rewrite the fraction as a percentageWhen the fraction has a denominator of 100, the numerator is the percentage; therefore, 4/6 converts to 66.6 percent.Alt..

What is a nonzero multiple?

If a question asks for the multiples of a number, most often it is asking for a list of products obtained by multiplying 1, then 2, then 3 (and so on) by the original number. If a question were to ask for the first two nonzero multiples of 2, the answer would be 2 and 4, as zero is specifically excluded because it is not a nonzero multiple. A zero multiple always equals zero, so there is no need to list it.

What is the surface area of a rectangular pyramid?

A right rectangular pyramid, with the apex direct above the center of the base, has two pairs of congruent triangular sides. In the case of a right square pyramid, all four triangular sides are congruent. The height of a triangular side is not equal to the height of the pyramid, but it can be derived by using the Pythagorean formula.

What is the way to find equivalent fractions?

Equivalent fractions are fractions that represent the same value, although the numbers in the fraction are different. When a fraction can no longer be divided by a whole number, the fraction has been reduced to its simplest form, or simplified. For example, 1/2 can no longer be divided by a whole number. Other equivalent fractions of 2/4 are 6/12, 8/16 and 10/20. Equivalent fractions can only be found by multiplying or dividing, not by adding or subtracting.Other types of fractions include proper, improper, reciprocal and mixed number. Proper fractions are fractions when the numerator is a sma..

Can a line segment have two midpoints?

For a line segment with endpoints (X1,Y1) and (X2,Y2), the midpoint of the line is ([(X1+X2)/2],[(Y1+Y2)/2]). If the line is parallel to the X axis, the Y coordinate is the same as the Y coordinate of the endpoint. If the line is parallel to the Y axis, the X coordinate is the same as the X coordinate of the endpoint.\nWhile a line segment has only one midpoint, it has an infinite number of bisectors. Bisectors are lines or line segments that pass through the midpoint of the line.

How do you graph piecewise functions?

Determine each sub-domainEach part of a piecewise function will be valid for certain values of x. Since the domain of the function includes all values that are valid for x, each part of the piecewise function has a sub-domain for which it is valid. For example, the function: \n f(x) = | x^2 for x ? 0\n | 1/x for x < 0\n\nhas a domain that includes the entire real number system, but x^2 only has a sub-domain from zero upwards, and 1/x only has a sub-domain of zero d..

What is a three-dimensional object?

In the physical world, most objects, such as chairs, desks, trees and people, are three-dimensional. Even paper, which seems like it has only two dimensions, is actually three-dimensional, for it has a very small depth. In geometry, examples of three-dimensional objects include spheres, cylinders, cones, cubes and pyramids. These solid objects are plotted on a coordinate system with three axes: the x-axis, the y-axis and the z-axis. Two-dimensional objects, such as squares and circles, are plotted on a two axis system with only an x-axis and a y-axis.An example of a three-dimensional object is..

How can you calculate the century of a given year?

For example, to calculate the century in which the year 1955 is, divide 1955 by 100. You will get 19.55. Drop the decimals and add one (19 + 1). The result is 20. Thus, 1955 is in the 20th century. Centuries are used in conjunction with the astronomical year numbering, which includes the year 0.\nEuropeans used a calendar that split time into whether it was before Christ, or after. This calendar had year 1 BC followed by year 1 AD. When calculating the first 100 years from 1 AD, the first century starts in year 1 AD and ends in 100 AD. The BC and AD are sometimes replaced with BCE and CE, resp..

What is the surface area of a cylinder?

A cylinder consists of two circles of the same size and the cylindrical area between them. The cylindrical area is essentially a rectangle curved in the third dimension. The formula to find the area of a circle is A = pi r^2, and for a rectangle, the formula is A = width * height. In a cylinder, the width of the rectangle is represented by the perimeter of the top circle, or 2pi * r. The expanded formula is represented by A = (pi * r^2) + (pi * r^2) + (2pi * r * h).
