Question

construct triangle if angle B is 70°,angle C is 90° and BC is 8cm​

Answer 1

Explanation:

Step 1: draw a straight line BC of 8cm

Step 2: then from point B draw an angle of 90° by following steps

• draw semicircle from C
• keep the radius same and cut arc from the line where the radius touches BC, again cute an arch from the first arch (keep the radius same)
• now bisect these two arch with help of compass
• after bisecting draw a line through it of 90°

Step 3: now from point B draw an angle of 70° till it joins the 90° angle. Now name the intersection point A.
