If the base of an isosceles right triangle is 5cm long, what is its area? Please say why,
Because it is an isosceles right triangle, the acute angle is 45 ° and the height on the bottom edge is divided into two isosceles triangles. You can know that the height is half of the bottom edge, that is, 2.5cm. In this way, you can calculate the area
The area of an isosceles right triangle is 5 square centimeters. Find its base and height
a=b
a*b/2=5
a^2=10=b^2
a^2+b^2=c^2,
c^2=20,
C = 2 times root 5,
H = root 5,
The base is 2 times the root number 5 and the high root number 5
