Question

construct a ∆ABC with BC=5cm , ∆B=40° , C=50°. draw an altitude from vertex A to the base BC. measure ∆ADC​

Answer 1

Answer:

draw BC = 5cm using protractor draw the angles of 40 degree and 50 degree from B and C respectively and mark point of intersection as A ABC is the required triangle . now draw a line XY passing through A parallel to BC now using this line make an angle of 90 degrees which intersect BC at D. now AD is perpendicular to BC of right triangle ABC .

Answer 2

Answer:

Draw a line BC 5cm and more than half distance of 5cm draw an arc both sides and join it and after joining A ,B join to A and C join to A and AB and BC are equal
