Question

Formula to find area and perimeter of a isosceles triangle

Answer 1

Answer:

Step-by-step explanation:

If you have an isosceles right triangle (two equal sides and a 90 degree angle), it is much easier to find the area. If you use one of the short sides as the base, the other short side is the height. Now the formula A = ½ b * h simplifies to ½s2, where s is the length of a short side.

For the isosceles triangle above the measure of the base is 14 and the measure of the two equal sides are 9 each. Therefore the perimeter of the isosceles triangle is the summer of the three sides, 14+9+9=32

Answer 2

Area:

base*height/2

perimeter:

2*(same side)+the different side
