Question

construct a triangle having perimeter and it's basic angle are 60 and 45 degree​

Answer 1

We have to construct a triangle with perimeter 6.4 cm and with basic angles 60∘ and 45∘.

Draw a line segment PQ of length 6.4 cm using a scale.

1. Draw a line segment XY of 6.4cm.

2. Draw ∠DXY = B = 60o and ∠EYX =∠C = 45o 3. Draw the angle bisector of ∠DXY and ∠EYX which interest each other at A.

4. Draw the perpendicular bisector of AX and AY which interest XY at B and C respectively.

5. Join AB and AC

Therefore ΔABC is the required triangle.

Now, we will draw the angle bisector of ∠XPQ by first marking points S and T. Then by taking S and T as centers, draw an arc.
