Mathematics for IGCSE & O level - Circle Theorems (Section 1 - No. 13)
Two equal chords AB and CD intersect at P inside the circle. What can you deduce about angles formed?
AP = BP
CP = DP
AP = CP
BP = DP
Wyjaśnienie
When chords are equal and intersect inside, corresponding segments are equal (AP=CP and BP=DP).
