Ordering Sides and Angles in Triangles

The sum of the angles in a triangle is always 180 degrees.

Angle C is 90 degrees (180 - 30 - 60 = 90).

Side BC is the longest side.

In a triangle, the larger the angle, the longer the opposite side.

It is an isosceles triangle.

An acute triangle is a triangle where all three angles are less than 90 degrees.

A right triangle is a triangle that has one angle equal to 90 degrees.

An obtuse triangle is a triangle that has one angle greater than 90 degrees.

The longest side in a right triangle is called the hypotenuse, which is opposite the right angle.

Area = 1/2 * base * height.
