Lesson 1 
Right Angle: A right angle is angle
measuring 90 degrees.

Acute Angle: An acute angle is angle
measuring less than 90 degrees.

Obtuse Angle: An obtuse angle is
angle measuring more than 90 degrees.

Problem: Classify the angle PQR


Step 1: Analyze the figure carefully.

Step 2: We can see from the
diagram that angle PQR is less than 90 degrees. PQR
is an acute angle.

Step 3: The
answer is: PQR is an acute angle.

Try
two practice problems. Do
the following:

A. Draw an acute angle. 

B. Draw an obtuse angle.
