Answer 1

Solutions: 1 Mark each

a) The length of all sides of the triangle is equal.
So it is an equilateral triangle.
b) In this triangle two sides are=6m
So it is an isosceles triangle.
c) In this triangle one of the angles is 90${}^{\circ }$, so the triangle is a right-angled triangle.
d) In this triangle, two angles are equal to 70${}^{\circ }$.So it is an isosceles triangle.
