Question

Use the figure to do the following:

Let the line AM be 0°.

• Draw the line MB. Measure the angle it makes with the line AM and write it near B. Note the semicircle that passes through B and joins the North and South Poles. Trace it. 
• Now join MC. Measure LAMC and write it next to C. Draw a semicircle that passes through 'C' and joins the North and South Poles.
• Draw a line that passes through point A at 0°, and joins the North and South Poles.

Answer 1

∠AMB = 70°
∠AMC = 85°
