Chapter 10.1, Problem 4CE

To determine

To name: some angles with certain measure.

Answer to Problem 4CE

Draw $45°,60°,90°$ other than 30 degrees.

Explanation of Solution

The angles $60°$ can be drawn from the following steps:-

Step 1: Draw a line $PQ$

Step 2: Take a radius from the line $PQ$ and draw an arc and named that point $M$ .

Step 3: From $M$ point draw another arc with same radius and named that point as $N$ .

Step 4: Join the point $P$ and $N$ , then $\angle NPQ=60°$

So, by using compass and straightedge, draw $45°,60°,90°$ other than 30 degrees.
