Quadrant 2, x = -4, y = 1

Quadrant 2, x > y

Quadrant 3, x = y

Quadrant 4, x coordinate of 4

x = 0, y bigger than 5

x = 3, y = 2

Right-angled, angle of 80 degrees, 2 acute angles

Isosceles, angle of 40 degrees, obtuse angle

Right-angled, angle of 30 degrees

Right-angled, isosceles

Isosceles triangle, 70 degrees

a + b = 20, a even, b prime, simplifies

ab = 24, a < b, simplifies

a + b = 15, a > b, does not simplify

Simplifies, a is prime, b is a square number

Simplifies, a is odd, b is even

Simplifies, a + b = 9

Does not simplify, even and odd
