Here in this problem, two triangles are given and we have to name the largest angle and the smallest angle of those two triangles.
00:10
Now, the first triangle, one side is 12, another side is 5 unit, another side is 10 unit.
00:19
Now, we know in a triangle, the largest angle is opposite to the longest side and the smallest angle is opposite to the shortest side.
00:29
This is because the size of an angle in a triangle is directly proportional to the length of its opposite side.
00:38
So for triangle a, b, c.
00:44
Here the largest side is a, b, which is 12 unit.
00:50
So the angle opposite to the longest side, that is, which is 12 unit, a .b, is angle c.
00:58
So here angle c is the largest angle and the smallest angle will be opposite to the smallest size.
01:15
Here, the smallest size is b, c, which is 5 unit and the angle opposite to b c is a...
