An angle whose measure is the sum of the measures of two right angles ...
A right angle measures 90°. If we sum the measures of two right angles:
90° + 90° = 180°
An angle of 180° is called a straight angle.
Thus, the correct answer is A: straight angle.
An angle whose measure is the sum of the measures of two right angles ...
Explanation:
An angle whose measure is the sum of the measures of two right angles is called a straight angle. Let's break down the explanation step by step.
1. Understanding right angles:
A right angle is an angle that measures exactly 90 degrees. It forms a square corner and is often represented by a small square in diagrams.
2. Sum of two right angles:
When we have two right angles, their measures add up to 180 degrees because 90 + 90 = 180. This is because a straight line forms a straight angle, which is a line that measures 180 degrees.
3. Defining a straight angle:
A straight angle is an angle that measures exactly 180 degrees, which is the sum of two right angles. It forms a straight line and has its vertex (the point where the two lines of the angle meet) in the middle of the line.
4. Conclusion:
Hence, an angle whose measure is the sum of the measures of two right angles is a straight angle. It is important to understand that a straight angle is different from a right angle, which measures 90 degrees. The sum of two right angles forms a straight angle, which measures 180 degrees.
Therefore, the correct answer is option A) straight angle.
