Lynn Byrd, Greg Byrd and, Chris Pearce Solutions for Chapter: Shapes and Symmetry, Exercise 3: Exercise 8.2

For the diagram shown, write down the letters of the lines that are tangent to the circle.

For the diagram shown, write down the letters of the lines that are chords of the circle.

This is part of Omar's homework.

Omar has made a lot of mistakes. Copy the diagram and correctly label the parts of the circle.

Marcus draws this diagram.

I can draw three chords inside a circle that makes an isosceles triangle.

Now inside the circle draw three chords that make a scalene triangle.

Marcus draws this diagram.

I can draw three chords inside a circle that makes an isosceles triangle.

Now inside the circle draw four chords that make a rectangle.

Zara draws this diagram.

 
I can draw four tangents to the circle to make a rhombus.

I know it is a rhombus because it has:

Two pairs of parallel sides

Four sides of equal length

Opposite angles are equal

Two lines of symmetry.

Draw a circle. Draw four tangents to the circle to make a square.
