This question asks, are the triangles congruent by sss or sas? if a piece is missing and can be proven, please state it and the rule or definition used.
00:13
So what we'll do here is first take a look at each figure and then we will determine if we can prove congruence.
00:22
Looking at number one, we can tell that yes, these two triangles are congruent.
00:28
There is something that is not marked here and it is bc being congruent to itself.
00:35
All right.
00:36
So we know that bc is congruent to bc.
00:45
That means that and the reason we know that is because of the reflexive property.
00:55
A reflexive property just says a figure is congruent to itself.
01:01
All right, we're going to go ahead and circle yes.
01:04
Now, the congruent statement is going to be triangle a, b, c is congruent to triangle dbc.
01:19
We have to make sure that the congruent sides are matching here.
01:25
So we know a, b is congruent to d, b.
01:28
So we have to write it in that order.
01:31
Let's take a look at the next one.
01:35
The next one says we have this figure where a, b, is congruent to ac...
