Question

construct a triangle sides 5cm 6cm 7cm and then a similar to it whose side are 3by4 of the corresponding sides of the first triangle​

Answer 1

Step-By-Step Explanation :

Making the triangle

Draw a line segment AB = 5 cm

Draw an arc at 6 cm from point A.

Draw an arc at 7 cm from point B so that it intersects the previous arc.

Joint the point of intersection from A and B.

This gives the required triangle ABC.

Dividing the base:

Draw a ray AX at an acute angle from AB

Plot three points on AX so that; AA

B and intersects AB at point B'

Draw a line from point B' parallel to BC so that this line intersects AC at point C'
