Answer:
Step-by-step explanation:
Triangle is an example of a polygon with three sides. The types of triangle we have are the equilateral, isosceles, scalene and right angled triangle.
An equilateral triangle is a triangle that has all its 3 sides and angles equal.
An isosceles triangle is a triangle that has two of its sides and angles equal.
A scalene triangle is a triangle that has none of its sides and angles to be equal.
According to the question, we are given a triangle of lengths 9, 10 and 130. It is seen that all the length of each sides of the triangle is different, this makes it a scalene triangle.
