Question

construct a ∆ ABC in which BC = 5 cm angle B=45° and AC - AB = 1.6 ​

Answer 1

Answer:

Triangle ABC is a equilateral triangle....steps to make are given below...

Step by step Explanation:

make a line segment of 5 cm and name it...BC.

as, AC = AB we know the angles opposite to these sides will be equal i.e. B=C

now make angles of 45 degrees from point B and C.

extend both lines.

the point where they intercept...mark is A

OR

mark arcs of 2.5 cm from point B and point C. the point where they intercept is point A.

Finally join A to B then to C.

Therefore the triangle is constructed.
