WebIn circle O, AD and BE are diameters. What is mAE? Solution: ∠AOB = ∠EOD = 3x (As they are vertically opposite angles) ∠AOB + ∠BOC = 90, i.e. 3x + 0.5x + 34 = 90. 3.5x + 34 = 90 . By … Webcircle O at point A, secant PBD intersects diameter AC at point E, m∠P =40, and mCD:mDA =1:8. Find mAD, mAB, m∠BEA, m∠BAC, and m∠PBA 8 In the accompanying diagram, B is the midpoint of AC, triangle ADC is inscribed in circle O, chords AC and BD intersect at E, PR → is a tangent to circle O at D, PAB is a secant, and mBA:mAD:mDC =2:3:5 .

Web1 If A, B, C, D are four points on a circle in order such that AB = CD. How do you prove that AC = BD. Share Cite Follow asked Feb 29, 2016 at 14:40 Indu 15 1 3 Feb 29, 2016 at 14:42 Te problem is I do not even know how to start with his problem. If I can be given a hint on how to start, I will try to figure this out.. Add a comment 2 Answers WebA diameter is a chord containing the circle’s center. To prove that a chord is a diameter you must show that it contains the center. Two arbitrary congruent chords may or may not contain the center. If they both contain the center, then they are both diameters. Let’s consider the case of two congruent chords that do not contain the center: high supply disposable vape pen review
