Circle Theorems
Flashcards do conjunto (9)
- 1—a = a
Angles joined by the same arc are equal - 2—c = 90°
A triangle inside a semi circle is right angled
- 3—a = 2b
The angle at the centre is double the angle at the circumference
- 4—a = c
b = d
Opposite angles in a cyclic quadrilateral add up to 180°
- 5—y + 130 = 180
x= 2y
- 6—s = 90°
t = 90°
S and t are right angles
- 7—Two angles in an isosceles triangle are the same
- 8—Opposite angles are the same
- 9—e = 81 + 73
e = 180 - 154
Angles on a straight line add up to 180
