The side of BC of an equilateral triangle Delta ABC is parallel to X-axis. Find the slopes of line along sides BC, CA and AB.

Find the height of an equilateral triangle of side x + 2.

Altitude AD of an equilateral triangle ABC is a diameter of circle. If circle intersect AB and AC at E and F then (EF)/(BC) =

In Delta ABC , internal angle bisector of angle A meets side BC in D. DE bot AD meets AC in E and AB in F. Then

In an equilateral triangle ABC, AD bot BC meeting BC in D then AD^2 =…………..

In Delta ABC , right angle is at B,AB = 5cm and angle ACB =30^(@) Determine the lengths of the sides BC and AC.

In Delta ABC, AB = BC then it is .......triangle .
