What does a 90 degree make angle option A obtuse angle B acute angle ...
Understanding AnglesAngles are formed when two lines meet at a point, and they can be classified based on their measure.
Types of AnglesTo determine what a 90-degree angle is, let's look at the four main types of angles:
- Acute Angle: This angle measures less than 90 degrees. It is sharp and small.
- Right Angle: A right angle measures exactly 90 degrees. It is often represented by a square corner, like in a piece of paper.
- Obtuse Angle: An obtuse angle measures more than 90 degrees but less than 180 degrees. It looks wide and open.
- Straight Angle: A straight angle measures exactly 180 degrees. It forms a straight line.
ConclusionWhen we analyze the options provided:
-
Option A: Obtuse angle – Not correct, as it exceeds 90 degrees.
-
Option B: Acute angle – Not correct, as it measures less than 90 degrees.
-
Option C: Straight angle – Not correct, as it equals 180 degrees.
-
Option D: Right angle – Correct! This angle measures exactly 90 degrees.
In summary, a 90-degree angle is classified as a right angle, making option D the right choice. Understanding these types of angles helps in various fields, including mathematics, art, and engineering.
