HELP ME ASAP PLEASE ?!!The triangles shown below must be congruent
a. true
b. false

Start by looking at the Properties of congruent triangle:

1. SSS -"side, side, side" and means that we have two triangles with all three sides equal

we are only given the length of one side in this triangle so we can not use this one to determine if the triangles are congruent or not.

2.SAS -"side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal.

once again, we are only given the length of one side in each triangle, so this one also cant help us to determine if the triangles are congruent.

3. ASA- "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal.

in the triangle to the right we get: ∠62, 7, ∠60

in the triangle to the left we get : ∠58, 7, ∠62

these do not match up with each other.

with this information we can determine that the triangles are not congruent therefore the answer is B. False

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
