1.The Pythagorean Theorem states that: "The square of the hypotenuse of a right angle triangle is equal to the sum of the squares of the other two sides." This means that, in a right triangle ABC with hypotenuse AC AB * AC = BC^2 (AB + AC)^2 = BC^2 AB^2 + BC^2 = AC^2

2.There is a right triangle PQR where: angle Q = 90 degrees; angle P = angle R. What is the measure of angles P and R? 45 degrees 60 degrees 75 degrees

3.There is a triangle XYZ where XY is perpendicular to YZ and angle X = 70 degrees. What is the measure of angle Z? 130 degrees 20 degrees 110 degrees

4. A right triangle, ABC, is given, where angle B = 90 degrees. The side AB is extended past angle B to form an exterior angle, X. What is the measure in degrees of angle X? 135 degrees 45 degrees 90 degrees

5. If the measure of one of the internal angles of a triangle is 95°, then which of the following cannot be the measure of remaining angles? 90° 80° 15°

6. If one angle of a triangle is obtuse, then which one of the following is the possible measure of remaining angles? 100° 105° 90°

7. The measure of base of an isosceles triangle is BC = b = 7/3 and the congruent sides are AB = a, AC = a = 4b, then its perimeter is 27 18 21

8. If the largest angle in a triangle is 70°, what is the least possible value of the smallest angle of the triangle? 30° 40° 10°
