Triangles: Problem Solving and Reasoning.
Name Image Description An irregular shape
One of the angles is a right angle
The other two add up to make the remaining 90°
A regular shape All three sides are equal All three angles are equal
(60°)
An irregular shape Two sides are equal in
length and one is different Two angles are equal in size
and one is different
An irregular shape None of the sides are the
same length None of the angles are the
same size
Triangles: Problem Solving and Reasoning
90°
Label and identify each type of triangle. The first one has been done for you.
Here is a square. Inside the square is an equilateral triangle. The perimeter (outside measurement) of the square is 160cm
Triangles: Problem Solving and Reasoning
From each line, draw two more sides to create: A equilateral triangle A scalene triangle An isosceles triangle If working in your book, it may be useful to know that each line measures 4cm.

This is Rosie.
She has 6 match sticks that she has been using to create the outline of different triangles.
Do you agree or disagree with what Rosie says?
Prove it!

Quadrilaterals.
?
All three inside angles add up to 360°
All the sides are straight
They are a 2D shape
They have four sides and four corners.
Quadrilaterals can be regular* or irregular*

Quadrilaterals: Problem Solving and Reasoning
a) Complete each of the boxes in the table by filling them with a different quadrilateral.
b) Which box cannot be filled in? Explain your reasoning. __________________ __________________________________________________________________
Use this box or draw in your books.

°. Use this statement to work out the missing angle. The first has been done for you with an explanation.
120° + 95° + 85° = 300° (First add up the angles that you know the measurements for. Use column addition if needed.) 360° - 300° = 60° (Next, subtract your answer from 360° to find the difference. Use column subtraction if needed.) D = 60°

Jottings box 110° + 87° + 65° = 262°
360° - 262° = 98°
G = 98°
Jottings box 95° + 85° + 85° = 265°
360° - 265° = 95°
Y = 95°

You may have observed that the bottom angles are the same so the top angles must also be the same when tackling this.
