An isosceles triangle is one which has any two of its sides equal in length. Since angles inside a triangle depend on the relation between the sides, two equal sides in an isosceles triangle imply that there are two angles in the triangle which measure the same amount of degrees. In this quiz, the child has to find out the area of the given isosceles triangle using the basic formula he or she knows. After completion of the quiz, the child would be understanding the key factors that have to be taken into account while finding the area of an isosceles triangle.

How to find area of an isosceles triangle ?

An isosceles triangle is a type of triangle that has two sides with the same length. These sides are called “legs,” and the third side is called the “base.”

To find the area of an isosceles triangle, we use a formula that involves the length of the base and the height of the triangle. The height of the triangle is the distance from the base to the top point of the triangle, called the “apex.”

To use the formula, we first need to draw a line from the apex of the triangle down to the base, creating two smaller triangles. This line is called the “altitude” of the triangle.

The formula for finding the area of an isosceles triangle is:

Area = (base * altitude) / 2

To use the formula, we need to measure the length of the base and the altitude, then plug those numbers into the formula. Let’s try an example:

Imagine we have an isosceles triangle with a base of 10 inches and an altitude of 8 inches. Plugging these numbers into the formula, we get:

Area = (10 * 8) / 2 = 40 / 2 = 20 inches

So the area of this isosceles triangle is 20 square inches.

It’s important to remember that the base and altitude must be in the same units, whether it’s inches, feet, or centimeters. Make sure to use the same units for both measurements when using the formula.

That’s all there is to it! Now you know how to find the area of an isosceles triangle. You can use this knowledge to solve math problems and even to measure the size of different shapes in the real world.
