In figure AB and CD bisect each other at O. State the 3 pairs of equal parts in ∆AOC and ∆BOD. Is ∆AOC ≅ ∆BOD? Give reasons

GuDViN [60]

Answer:

SEE EXPLANATION

Step-by-step explanation:

$In\:\triangle AOC \:\&\:\triangle BOD$

$AO \cong OB.... (given)$

$\angle AOC \cong\angle BOD$

$(vertical \: \angle s)$

$CO \cong OD.... (given)$

$\therefore \triangle AOC \:\cong\:\triangle BOD$

$(SAS \: postulate)$

So, the 3 pairs of equal parts in ∆AOC and ∆BOD are:

$AC = BD$

$m\angle OAC = m\angle OBD$

$m\angle OCA = m\angle ODB$

Hey can I have some help with this I am very confused

aniked [119]

m<5=40°

Reason-Its Given

m<2=140

Reason-Given

<5 and <2 are linear pair(looked properly in diagram) Hence they are supplementary.

<5 and 2 are same side interior angles (Clearly shown on diagram .

We can call them co responding interior angles and their sum will be 180 if lines are parallel

a||b

Let's verify

Let the angle below <1 be <3

Now

<2+<3=180

<5+<4=180

<5=<2

$\\ \sf\longmapsto$

Hence verified
