How do i find the area of the isosceles triangle?

Use the Pythagorean Theorem to find 'h'.



For right triangles, where 'a' and 'b' are the two legs and 'c' is the hypotenuse.

Divide the base by 2 to find the base length of one of the right triangles. 32/2 = 16. Now apply the Pythagorean Theorem:



Simplify:



Subtract 256 to both sides:



Take the square root of both sides:



So the height is 12cm. Apply the formula for the area of a triangle:

Number 5 is 50 degreesnumber 6 is 45 degreesnumber 7 is 60 degreesnumber 8 is 45 degrees
