-- Each number has to be (more than the difference of the other two) but (less than their sum).
-- Count the lengths of the sides. If you get to three and then run out of numbers, it's a triangle.
Information about the lengths of two sides of a triangle is insufficient to determine its area.
If all 3 sides are equal: Equilateral Triangle If 2 sides are equal: Isosceles Triangle If all 3 sides are unequal/different: Scalene Triangle
The 3 sides have different lengths
If the lengths of each pair of them add to more than the length of the third, they can form a triangle. If not, they cannot.
A square's sides have equal lengths, and an equilateral triangle's sides also have equal lengths.
Information about the lengths of two sides of a triangle is insufficient to determine its area.
If the lengths of the sides of the triangle can be substituted for 'a', 'b', and 'c'in the equationa2 + b2 = c2and maintain the equality, then the lengths of the sides are a Pythagorean triple, and the triangle is a right one.
If all 3 sides are equal: Equilateral Triangle If 2 sides are equal: Isosceles Triangle If all 3 sides are unequal/different: Scalene Triangle
A scalene triangle has 3 sides of different lengths An isosceles triangle has 2 sides of equal lengths An equilateral triangle has 3 sides of equal lengths
The 3 sides have different lengths
All three sides have different lengths.
An isosceles triangle has 3 sides 2 of which are equal in lengths An equilateral triangle has 3 sides all of which are equal in lengths
First, it is necessary to know three sides of what - most likely a triangle but the question does not say so. If a triangle, the difference of two sides is not sufficient to determine the lengths of the three sides.
If the lengths of each pair of them add to more than the length of the third, they can form a triangle. If not, they cannot.
A square's sides have equal lengths, and an equilateral triangle's sides also have equal lengths.
A scalene triangle has sides of different lengths while an equilateral triangle has sides of equal lengths
An EQUILATERAL triangle has all three sides the same length. An ISOSCELES triangle has two sides with the same length. A SCALENE triangle has all three sides different lengths.
