Sample Answers and Explanations for Chapter 3 Chapter Test A
1. In a triangle ABC, angle A measures 40 degrees and angle B measures 70 degrees. What is the measure of angle C?
Answer: To find the measure of angle C, we can use the fact that the sum of the angles in a triangle is always 180 degrees. So, we subtract the measures of angles A and B from 180. Thus, angle C = 180 – 40 – 70 = 70 degrees.
2. Given that triangle PQR is an isosceles triangle with PQ = PR, if angle P measures 60 degrees, what is the measure of angle R?
Answer: In an isosceles triangle, the base angles are congruent. Therefore, angle P = angle R. Since angle P measures 60 degrees, angle R also measures 60 degrees.
3. Triangle XYZ is a right triangle with XY = 6 cm and YZ = 8 cm. What is the length of side XZ?
Answer: Using the Pythagorean theorem, we can find the length of side XZ. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. So, we can set up the equation: 6^2 + x^2 = 8^2. Solving for x, we find x = √(8^2 – 6^2) = √64 = 8 cm. Therefore, the length of side XZ is 8 cm.
4. Given that triangle ABC is an equilateral triangle with side length 10 cm, what is the measure of each angle?
Answer: In an equilateral triangle, all angles are congruent and measure 60 degrees. Therefore, each angle in triangle ABC measures 60 degrees.
5. In triangle DEF, the measure of angle D is twice the measure of angle F, and the measure of angle E is 30 degrees less than the measure of angle F. What are the measures of angles D, E, and F?
Answer: Let x be the measure of angle F. Since angle D is twice the measure of angle F, angle D = 2x. Angle E is 30 degrees less than angle F, so angle E = x – 30. The sum of the measures of the angles in a triangle is 180 degrees, so we can set up the equation: 2x + x + (x – 30) = 180. Solving for x, we find x = 70. Therefore, angle D = 2 * 70 = 140 degrees, angle E = 70 – 30 = 40 degrees, and angle F = 70 degrees.
