WebThe angle bisector theorem tells us the ratios between the other sides of these two triangles that we've now created are going to be the same. So it tells us that the ratio of AB to AD is going to be equal to the ratio of BC to, you could say, CD. So the ratio of-- I'll color code it. Web11 dec. 2024 · Median AD drawn from A is ⊥ to BC then b is Q4. From the following diagram the line segment XY is parallel to side AC of ABC and it divides the triangle into two parts of equal areas then AX / AB = Q5. From the following diagram AD ⊥ BC and AD ⊥ EF. If ∠EAB = ∠FAC, AB = 2x + 3, AC = 3y + 1, BD = x and DC = y + 1 then the values of x … Web10 nov. 2024 · 13. ∆ ABC is right triangle in which ∠A = 90° and AB = AC. The values of ∠B and ∠C will be: (a) ∠B = ∠C = 60° (b) ∠B = ∠C = 30° (c) ∠B = ∠C = 45° (d) ∠B = ∠C = 50° 14. If the vertical angle of a isosceles triangle is 40° then measure of other two angles will be: (a) 60° 60° (b) 70° 70° (c) 50 50° (d) 75° 75° 15. couch to 5k burlington
