Construct such that . Measure other angles of the of the triangle. What type of triangle is this?
STEPS OF CONSTRUCTION:
STEP 1: First we draw a line segment of length .
STEP 2: Now we make a ray making an angle of .
STEP 3: With as centre and as radius draw an arc intersecting at .
STEP 4: Now join and we get the required triangle .
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,
