Amardeep and Rajvi have just bought a new house, they would like
to carpet two rooms in their house.
In their bedroom they would like a navy blue carpet, the length of
the room is 11 metres and the width is 7 metres. What area of

WALT: tell what an isosceles, scalene, and equilateral triangle looks
like, to measure the sides of a triangle.
What do you know about triangles?
Types of triangles
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
Scalene Triangle
No Sides of equal Length
All interior angles are different
Right-Angled Triangles
Right-Angled Triangles can be either Isosceles or scalene
triangles
They have an Interior angle of
Scalene Right Angled Triangle
90 degrees
Isosceles Right Angled Triangle
How do we draw these triangles and how do we measure the degrees of
the different angles using the protractor.
WALT: tell what an isosceles, scalene, and equilateral triangle looks
like, to measure the sides of a triangle.
TASK
You need to make the different types of triangles using art
straws.
Can you then come up with their own way to record each
triangle and label it with facts about the three types of
triangles.
