The external angle is suplementary to the internal angle close to it. We also know that the sum of all the internal angles of the triangle are equal to 180 degrees, this means that the angle "a" is suplementary to the sum of the angles "b" and "c". Through this logic, we can conclude that since:
Then we can conclude that:
Therefore the statement is true, the exterior angle is equal to the sum of its remote interior angles.
Let's use an example:
On this example, the external angle is 120 degrees, therefore the sum of the remote interior angles must also be equal to that. Let's try:
The sum of the remote interior angles is equal to the external angle.

Answer:
A = (1/2) * b * h
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as obtuse, scalene, right angle, equilateral and isosceles triangle.
The area of a triangle is half the product of the base of the triangle and the triangle height. The area is given by the formula:
A = (1/2) * b * h
A = (1/2)bh = 0.5bh
Where A is the area of the triangle, b is the bae of the triangle and h is the height of the triangle.
Answer:
B
