Test your understanding of adjacent angles with these short Grade 5 geometry challenges. Think through each problem before revealing the answer.

Question 1: Two adjacent angles measure 38° and 27°. What is their combined angle measure?

Reveal answer and explanation

Answer: 65°.
Explanation: Add the adjacent angles: 38° + 27° = 65°.

Question 2: A whole angle measures 112°. One part measures 49°. What is the other part?

Reveal answer and explanation

Answer: 63°.
Explanation: Subtract the known part from the whole: 112° − 49° = 63°.

Question 3: True or false: Two angles are adjacent if they share a vertex, even when their interiors overlap.

Reveal answer and explanation

Answer: False.
Explanation: Adjacent angles share a common vertex and a common side, and their interiors do not overlap.

Question 4: Two adjacent angles measure 44° and 46°. What is their combined measure?

Reveal answer and explanation

Answer: 90°.
Explanation: 44° + 46° = 90°. This is a right angle.

Question 5: A whole angle is 130°. One part is 75°. Find the other part.

Reveal answer and explanation

Answer: 55°.
Explanation: 130° − 75° = 55°.
