Question

construct a triangle ABC whose perimeter is 12 cm angle B equals to 60 degree angle C equals 45 degree​

Answer 1

Answer:

We are given that perimeter of triangle = 12 cm, ∠B = 600 and ∠C = 450 Steps of Construction (i) Draw a ray PX and cut off a line segment PQ = 12 cm from it. (ii) At P, construct ∠YPQ = 300 (1/2 × 600). (iii) AT Q, construct ∠ZOP = 22.50 (1/2 × 450) (iv) Let the rays PY and QZ intersect at A. (v) Draw the perpendicular bisector of AP intersecting PQ at a point B. (vi) Draw the perpendicular bisector of AQ intersecting PQ at a point C. (vii) Join AB and AC. So, Δ ABC is the required triangle.Read more on Sarthaks.com - https://www.sarthaks.com/72065/construct-a-triangle-abc-whose-perimeter-is-12-cm-b-60-0-and-c-45-0
