Exercises 2
Directions: Apply the 45°-45°-90° Right Triangle Theorem or the 30°-50-90Right Triangle
Theorem to find the missing measure of the side of the right triangle. Show solutions.

1. The hypotenuse of an isosceles right trapezoid measures 9 cm. How long is each leg?
(Hint: Leg/= times the length of the hypotenuse)

2. What is the perimeter of a 30"- 60°-90" Right Triangle, whose shorter leg is 7 inches long?
(Hint: Perimeter of triangle = a + b + c, where a, b, c are sides of triangle)

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).
