Example Question #8 :How To Find The Area Of A Right Triangle
An equilateral triangle has a side of.
What is the area of the triangle?
An equilateral triangle has three congruent sides. The area of a triangle is given bywhereis the base andis the height.
The equilateral triangle can be broken into tworight triangles, where the legs areandand the hypotenuses is.
Using the Pythagorean Theorem we getorand the area is
Example Question #1 :How To Find The Area Of A Right Triangle
The hypotenuse of atriangle measures eight inches. What is the area of this triangle (radical form, if applicable)?
It is impossible to tell from the information given.
In a, the shorter leg is half as long as the hypotenuse, and the longer leg istimes the length of the shorter. Since the hypotenuse is 8, the shorter leg is 4, and the longer leg is, making the area:
