Construct a triangle ABC, in which ∠B = 53.13°, ∠C = 36.87° and AB + BC+ CA = 24 cm. What type of triangle is this?
Steps-
-Draw line segment PQ of length 24 cm. From P draw ray PL which makes angle 53.13∘ with PQ using a protractor. Similarly, draw ray QM which makes angle 36.87∘ with PQ.
-Using angle bisector construction method, draw angle bisectors for angles APQ and angle AQP. Let these 2 angle bisectors meet at A.
-Using perpendicular bisector construction method draw perpendicular bisectors DE for AP and FG for AQ respectively.
-Let the point where DE meets PQ be B and let the point where FG meets PQ be C. Join AB and AC. The required triangle is triangle ABC, which is right - angled triangle.
