Answer:
Triangle is a three(3) sided shape i.e it has 3 sides and angles. Triangle can classify based on its side (length and equality) and size of its angles.
Step-by-step explanation:
A, Classification by sides: There are three types of triangle base on sides. These are:
1. Scalene Triangle : This describe triangle that has none of its side to be equal. i.e none of the three sides has no equal length.
2. Isosceles Triangle : This describe triangle that has two of its side equal. Also two of the angles are equal.
3. Equilateral Triangle : This describe triangle that has all its side equal i.e all three sides have equal length. Also all angles are of equal sizes.
B. Classification by size of angle: There are four types of triangle base on classification by angle:
1. Acute Triangle : This describe triangle with all three angles less than 90 degree.
2. Obtuse Triangle : This describe triangle that has one of its angle greater than 90 degree
3. Right Angled Triangle : This describe triangle with one of its angle equal 90 degree.
The sum of the interior angles in a regular polygon is given by the formula 180<span>(n – 2), where n is the number of sides in the polygon. An octagon has </span>eight<span> sides, so the sum of the angles of the octagon is </span>180<span>(8 – 2) = </span>180(6<span>) = 1080 degrees. In other word your answer would be an octagon.
