00:00:00,780 --> 00:00:06,190
In this video, let's discuss the SS congruence criteria.

2
00:00:06,570 --> 00:00:09,420
All right, say your given triangle, ABC.

3
00:00:09,750 --> 00:00:12,510
Now, what does SS stand for?

4
00:00:12,660 --> 00:00:16,120
Its side included angle and side.

5
00:00:16,140 --> 00:00:21,780
So that is your given two sides of this triangle and you are given and included angle.

6
00:00:21,990 --> 00:00:29,070
Say, for example, you're given the measure of site B, C as five centimeter, the measure of side

7
00:00:29,070 --> 00:00:31,620
A, B as six centimeter.

8
00:00:31,860 --> 00:00:34,160
And you're given this angle over here.

9
00:00:34,170 --> 00:00:37,020
Six hundred degrees, for example.

10
00:00:37,050 --> 00:00:37,410
All right.

11
00:00:37,620 --> 00:00:42,680
So you're given two sides and the included angle between those two sides.

12
00:00:42,930 --> 00:00:45,740
That's what we mean with SS criteria.

13
00:00:45,940 --> 00:00:46,370
All right.

14
00:00:46,530 --> 00:00:53,700
Now, to establish that this is a valid congruence criteria, all we need to check is whether we can

15
00:00:53,700 --> 00:00:59,570
draw a copy of Triangle ABC just having these three pieces of information.

16
00:00:59,700 --> 00:01:08,400
If that is true, if we can draw one triangle without any ambiguity with just these three measures and

17
00:01:08,400 --> 00:01:14,920
that triangle is an exact copy of triangle ABC, then S.A.S. is a valid congruence criteria.

18
00:01:15,180 --> 00:01:16,800
Let's check it over here.

19
00:01:16,800 --> 00:01:19,330
We have the measure of BK's five centimeter.

20
00:01:19,650 --> 00:01:24,520
So let me draw a line segment over here such that this is also five centimeter.

21
00:01:24,960 --> 00:01:25,400
All right.

22
00:01:25,680 --> 00:01:27,680
Now we know this angle is hundred degrees.

23
00:01:27,840 --> 00:01:34,170
So let me construct an angle over here such that this measure is equal to a hundred degrees.

24
00:01:34,260 --> 00:01:34,640
Right.

25
00:01:35,580 --> 00:01:36,110
All right.

26
00:01:36,360 --> 00:01:38,460
And now let me take my compass.

27
00:01:38,760 --> 00:01:47,130
If the sharp edge at point R and draw an arc with radius six centimeter such that it cuts this line

28
00:01:47,130 --> 00:01:48,200
segment over here.

29
00:01:48,540 --> 00:01:49,830
So it cuts it over here.

30
00:01:50,010 --> 00:01:58,980
And let's mark that point as point B and join P to Q So in this way we have successfully drawn a copy

31
00:01:58,980 --> 00:02:07,530
of the given triangle ABC as p r q This means if we have two triangles and we know that two sides are

32
00:02:07,530 --> 00:02:15,380
equal and the angle between those two sides are equal, then those two triangles are congruent.

33
00:02:15,510 --> 00:02:19,770
That is SS is a valid congruence criteria.

34
00:02:19,770 --> 00:02:20,790
Checking RUO.
