Sample Questions and Detailed Solutions from American School Geometry Exam 7

Below are some representative problems with answers and explanations to guide your preparation.

Question 1: Find the measure of angle ABC in a triangle ABC, where angle A is 50° and angle B is 60°.

Solution:

• Recall that the sum of interior angles in a triangle is 180°.
• Calculate angle C: 180° - (angle A + angle B) = 180° - (50° + 60°) = 70°.
• Answer: The measure of angle ABC (angle C) is 70°.

Question 2: In a circle with center O, chord AB is 8 cm long, and the distance from O to AB is 3 cm. Find the length of the radius of the circle.

Solution:

• Draw the radius lines from O to points A and B, and drop a perpendicular from O to AB, bisecting AB at point D.
• In right triangle ODB:
• OD = 3 cm (distance from O to AB)
• BD = AB/2 = 4 cm (since D is midpoint)
• Apply Pythagoras theorem:
• OB² = OD² + BD²
• OB² = 3² + 4² = 9 + 16 = 25
• OB = √25 = 5 cm
• Answer: The radius of the circle is 5 cm.

Question 3: Prove that the angles in a parallelogram are supplementary.

Solution:

• In a parallelogram, opposite angles are equal, and consecutive angles are supplementary.
• Using the property that consecutive angles in a parallelogram are supplementary:
• Angle 1 + Angle 2 = 180°
• To prove:
• Draw the parallelogram ABCD.
• Show that the adjacent angles add up to 180° by using alternate interior angles or parallel lines.
• Conclusion: The sum of consecutive angles in a parallelogram is 180°, hence, they are supplementary.

Question 4: Find the area of a trapezoid with bases measuring 10 cm and 14 cm, and height 6 cm.

Solution:

• Use the trapezoid area formula:
• Area = ½ × (sum of bases) × height
• Calculation:
• Area = ½ × (10 + 14) × 6 = ½ × 24 × 6 = 12 × 6 = 72 cm²
• Answer: The area of the trapezoid is 72 square centimeters.

Question 5: Determine whether the triangles with sides of lengths 7 cm, 24 cm, and 25 cm are right triangles.

Solution:

• Use the Pythagorean theorem:
• Check if the sum of squares of the shorter sides equals the square of the longest side.
• Calculation:
• 7² + 24² = 49 + 576 = 625
• 25² = 625
• Since they are equal, the triangle is a right triangle.
• Answer: Yes, the triangle with sides 7 cm, 24 cm, and 25 cm is a right triangle.

Common Mistakes to Avoid

• Misreading questions: Always double-check what is being asked.
• Ignoring diagrams: Draw your own if needed; diagrams clarify the problem.
• Forgetting to verify solutions: Recalculate or recheck your steps.
• Overlooking geometric theorems: Remember key properties, especially for proofs and constructions.
