In the figure below, `A C` and `B E` are parallel lines.
Are the lengths of BC and DE equal? Why? Are BC.and DE parallel? Why?

In the figure. below, the lines A B and CD are parallel and M is the mid point of A B . i) Compute the angles of Delta AMD, triangle MBC and Delta DCM? ii) What is special about the quadrilaterals AMCD and MBCD?

In the figure, A B C D E is a pentagon with all sides of the same length and all angles of the same size. The sides A B ." and AE extended, meet the side CDextended at P and Q . i). Are the sides of Delta BPC equal to 'the sides of Delta EQD? Why? ii) Are the side of AP and AQ of triangle APQ equal? Why?

In the figure BC=a,CD=b.Then prove that a=3b.

In the picture below, the side AC of the triangle ABC is extended by D, by adding the length of the side CB. Then the line through C parallel to DB is drawn to meet AB at E. Prove that CE bisects angle C

In the figure, angle A= 30^circ ,angle B= 90^circ , A C=16cm (a) What is the length of BC? b) What is the length of AB ?
