Common Geometry Chapter Assessment Questions and Their Answers
Question 1: Find the measure of an angle in a triangle where the other two angles are 45° and 60°.
Answer: The sum of angles in a triangle is 180°. Therefore, the missing angle is:
180° - (45° + 60°) = 75°
So, the measure of the missing angle is 75°.
Question 2: Prove that the diagonals of a rectangle are equal in length.
Answer: In a rectangle, opposite sides are equal and all angles are 90°. Using the coordinate method or the Pythagorean theorem, the diagonals are found to be equal because they are the hypotenuses of congruent right triangles formed by the sides of the rectangle.
Question 3: Calculate the area of a circle with a radius of 7 cm.
Answer: The area of a circle is given by:
A = πr²
= 3.14 × 7²
= 3.14 × 49
= 153.86 cm²
Therefore, the area is approximately 153.86 cm².
Question 4: Find the volume of a cylinder with a radius of 3 meters and height of 10 meters.
Answer: Volume of a cylinder is given by:
V = πr²h
= 3.14 × 3² × 10
= 3.14 × 9 × 10
= 3.14 × 90
= 282.6 m³
Thus, the volume is approximately 282.6 cubic meters.
