Triangles

Shapes with 3 sides!

Equilateral Triangle

All 3 Sides are equal in Length

All 3 interior angles are the same

Isosceles Triangle

Two Sides of equal Length

Two interior angles are the same

Page 4: Triangles Shapes with 3 sides! Equilateral Triangle All 3 Sides are equal in Length All 3 interior angles are the same

Scalene Triangle

No Sides of equal Length

All interior angles are different

Page 5: Triangles Shapes with 3 sides! Equilateral Triangle All 3 Sides are equal in Length All 3 interior angles are the same

Right-Angled Triangles

They have an Interior angle of 90 degrees

Right-Angled Triangles can be either Isosceles or scalene triangles

A Right Angled Triangle

Triangles

A Right Angled Triangle is different

It may be scalene or it may be isosceles

But it always has a right angle!

Triangles

Properties of a Right Angled Triangle

Has 1 right angle

May be an isosceles triangle

May have 1 line of symmetry

Is an irregular shape

It will be isosceles and have 1 line of symmetry when these 2 sides are equal.
