A perpendicular drawn from a vertex to the opposite side of a triangle is known as (a) an altitude (b) a median (c) an angle bisector (d) a bisector

Altitudes the perpendiculars drawn from the vertices of a triangle to the opposite side are known as the altitudes of the triangle.

Altitudes the perpendiculars drawn from the vertices of a trriangle to the opposite side are known as the altitudes of the triangle.

Line segments joining the vertices to the mid- points of the opposite sides to a triangle are known as medians (b) altitudes (c) heights (d) angle bisectors

The length of the perpendicular drawn from a vertex to opposite side of an equilateral triangle is '12 cm'. Calculate its perimeter and area.

Line segments joining the vertices to the mid-points of the opposite sides to a triangle are known as (a) medians (b) altitudes (c) heights (d) angle bisectors
