Identifying Basic Angles

Identifying Basic Angles

By Destiny McAlpine

• two straight lines that intersect at 90 degrees

• ​All triangles with one angle right are called right-angled triangles.

​

​Right Angle

​

• Measurements between 0 degrees and 90 degrees

​Acute Angle

​

• Greater than 90 degrees but less than 180 degrees​

​

​Obtuse Angle

​

• A straight angle is formed by rotating one ray by 180°with respect to another ray.
