Types of Triangles Thursday, 11 April 2019

The equilateral triangle Properties All sides are of the same length All angles are of the same size, 60 It has three lines of symmetry It has rotational symmetry of order 3

2. The isosceles triangle Properties Has two sides of the same length Has two angles are of the same size It has one line of symmetry

3. The right-angled triangle Properties Has one angle of 90

3. The scalene triangle Properties All three sides are of different lengths

Right-angle Isosceles Scalene Example Write down the name for each of the following triangles (a) Right-angle (b) Isosceles (c) Scalene

(d) Scalene (e) Isosceles (f) Equilateral
