4. Lengths of sides of triangle are √26, √26 and √32 therefore it is an isosceles triangle.
5. Gradient of AB = 2/3 and gradient of BC = 2/3. As point B is common the points A,B and C must be in a straight line.
6. Gradient of both lines is 0.25
7. Lengths of sides are 8, 5 and 5 therefore the triangle is isosceles.
8. x =1
9. y = 5
10. Midpoint of line joining (1, 2) and (7, 2) is (4, 2) and midpoint of line joining (4, 1) and (4, 5) is (4, 2).
The centre of the circle is (4, 2)
