I WONDER - What Do The Angles Add Up To In A Triangle?

The video explains how to determine the third angle in a triangle by knowing that the sum of all angles is 180 degrees. It provides an example where two angles add up to 70 degrees, making the third angle 110 degrees. The video also discusses the relationship between the sides and angles of a triangle, noting that the longest side is opposite the largest angle, and the shortest side is opposite the smallest angle. In right-angled triangles, the longest side is called the hypotenuse, which is opposite the right angle.

If two angles in a triangle are 50 degrees and 60 degrees, what is the measure of the third angle?

• 90 degrees

• 100 degrees

• 80 degrees

• 70 degrees

In a triangle, which side is opposite the largest angle?

• The shortest side

• The side opposite the smallest angle

• The longest side

• The side adjacent to the largest angle

Which side of a triangle is opposite the smallest angle?

• The longest side

• The hypotenuse

• The side adjacent to the smallest angle

• The shortest side

What is the longest side of a right-angled triangle called?

• Base

• Adjacent

• Hypotenuse

• Opposite

In a right-angled triangle, the hypotenuse is opposite which angle?

• The angle adjacent to the hypotenuse

• The largest angle
