Q24 In Figure Oa Ob Oc Od Show That Za 2c And 2b 2d D C Filo Since oa = oc and ob = od, triangles oac and obd are isosceles triangles. in an isosceles triangle, the base angles are equal. therefore, in triangle oac, ∠oac = ∠oca, and in triangle obd, ∠obd = ∠odb. since ∠oac = ∠oca and ∠obd = ∠odb, it follows that ∠a = ∠c and ∠b = ∠d. ∠a = ∠c and ∠b = ∠d. question 4: [25 marka!. Q24 (b) of 2025 pyq standard set 30 2 1 in the given figure, oa . ob = oc . od. show that a = c and b = d .more.

In The Given Figure Oa Ob Oc Od Show That тиаa тиаc And тиаb тиаd Show that ∠ a = ∠ c and. In fig., o is a point in the interior of a triangle abc, od ⊥ bc, oe ⊥ ac and of ⊥ ab. show that: o a^ 2 o b^ 2 o c^ 2 − o d^ 2 − o e^ 2 − o f^ 2 = a f^ 2 b d^ 2 c e^ 2. 1 manipulate the given equation to establish a proportion. we are given oa * ob = oc * od. divide both sides by ob * od to get: oa od = oc ob 2 identify the triangles to be proven similar. consider triangles aod and cob. we want to show that these triangles are similar. Hint: in this question it is given that in the above figure oa = ob and od = oc, we have to show that a o d and b o c are congruent to each other and the line ad and bc are parallel.

Example 6 Oa Ob Oc Od Show That A C And B D 1 manipulate the given equation to establish a proportion. we are given oa * ob = oc * od. divide both sides by ob * od to get: oa od = oc ob 2 identify the triangles to be proven similar. consider triangles aod and cob. we want to show that these triangles are similar. Hint: in this question it is given that in the above figure oa = ob and od = oc, we have to show that a o d and b o c are congruent to each other and the line ad and bc are parallel. We know that corresponding parts of congruent triangles are equal. ∴ ab = cd. hence, proved that ab = cd. in the adjoining figure, oa ⊥ od, oc ⊥ ob, od = oa and ob = oc. prove that ab = cd. Answer: explanation: given: oa × ob = oc × od to prove: ∠a = ∠c and ∠b = ∠d now, oa .ob = oc.od ∠aod = ∠cob (vertically opposite angles) ∴ aod ~ cob (by sas similarity criterion) we know that if two triangles are similar then their corresponding angles are equal. ⇒ ∠a = ∠c and ∠b = ∠d hence proved. Given, o is the point of intersection of two chords ab and cd. also, ob = od. we have to find the type of triangles oac and odb. chord intersection theorem states that when two chords inside the circle intersect each other then the product of their segments are equal. so, the product of segments, oa × ob = oc × od. so, oa = oc and ob = od. To approach this task, students should first identify the given information: oa = ob, oc = od, and ∠aob = ∠cod. the goal is to prove that ac = bd. a common strategy for such problems is to look for triangles that contain the sides ac and bd. in this case, we can consider triangles aoc and bod.
