Solution

STEPS OF CONSTRUCTION:

STEP 1: First we draw a line segment MP of length 5cm.

STEP 2: Now we make a ray PX making an angle of MPX=90°.

STEP 3: With P as centre and 5cm as radius draw an arc intersecting PX at A.

STEP 4: Now join AM and we get the required triangle AMP.

Now two sides of this triangle are equal it is an isosceles triangle. So the other two angles must be equal.

By angle sum property of triangle,

MAP+MPA+AMP=180°x+90°+x=180°2x+90°=180°2x=180°-90°2x=90°x=90°2=45°

AMP=PAM=45°
