Question

Draw a circle of radius 2.5 cm draw a triangle of angles 40*, 60*, 80*. With all the sides touching on circle

Answer 1

Δ ABC with angles 40° , 60° & 80° is Constructed with touching all the sides on circle of radius 2.5 cm

Step-by-step explanation:

Step 1 : Draw a circle of radius = 2.5 cm with center O, take any point M on circumference and Join OM

Step 2 : Draw an angle of 180° - 80° = 100° at MO such that it meets circle at N

Step 3 : Draw ⊥ at OM  &  ON such that they intersect at point A

Step 4 : Draw an angle of 180° - 60° = 120° at MO opposite to earlier drawn angle such that it meets circle at P

Step 5 : Draw perpendicular on MP both sides

Step 6 : Extend AM & AN Such that it intersects ⊥ drawn in step 6 at B & C

Δ ABC is Constructed with touching all the sides on circle of radius 2.5 cm
