In the adjoining figure: (i) Name the vertex opposite to side PQ. (ii) Name the side opposite to vertex Q. (iii) Name the angle opposite to side QR. (iv) Name the side opposite to ∠R

Look at the figures given below and classify each of the triangles according to its (a) Sides (b) Angles

Will an altitude always lie in the interior of triangle? If no, draw a rough sketch to show such a case.

6. Draw rough sketches for the following: (i) In ΔABC, BE is a median of the triangle.

(ii) In ΔPQR, PQ and PR are altitudes of the triangle.

(iii) In ΔXYZ, XL is an altitude in the exterior of the triangle.

Take an equilateral triangle and draw its medians and altitudes and check that the medians and altitude are same.
