The angles inside any triangle sum to 180 degrees. Isosceles simply means two sides are the same length.
The list that accompanies the question doesn't contain any numbers that could be the lengths of the sides of a triangle.
An isosceles triangle has two sides with equal measures. The third side can be any length.
A question without any equal sides is a scalene triangle. A scalene triangle, by definition, is a triangle without any congruent sides. Of course, there are varying definitions, but they all have the same gist. Once again, a triangle without any equal sides is a scalene triangle!
A triangle may or may not be a regular polygon. Let's look into things.First, a triangle is a polygon. All triangles are polygons. To be a regular polygon, the polygon must have equal sides. If the triangle has sides of equal length, then that triangle is an equilateral triangle and a regular polygon. If the triangle doesn't have sides of equal length, then it isn't a regular polygon. But in any case, the triangle is a polygon.
An isosceles triangle has two sides that are the same length. A scalene triangle does not have any sides that are the same length.
An isosceles triangle has two sides the same length. An equilateral has all 3 sides the same length. A scalene triangle doesn't have any sides that are the same length.
A scalene triangle
any 'isosceles' triangle
Any length you can think of, as long as two of its sides are the same length.
that depends on the triangle. if the triangle has no two sides that are the same length, then it is called a scalene triangle and it has no lines of symmetry. if the triangle has two sides that are the same length, the triangle has one line of symmetry, starting at the angle where the two same length sides meet, and ending at the center of the opposite side. if all three sides are the same length, the triangle has three lines of symmetry, between any angle an the center of the opposite side.
Any isosceles triangle will have 2 sides that are the same length so this would be an isosceles triangle.
20. There are 3 sides to any triangle. For an equilateral triangle all 3 sides are the same length. Therefore for this triangle we can say that, where x equals the length of a side: 3x = 60 x = 60/3 x = 20
An isosceles triangle is any triangle with two sides of equal length.
Oh heavens no. A QUADrilateral means that it has 4 sides and the definition of a triangle is three sides. An isosceles triangle is specifically a triangle with two sides of the same length and one with a different length. You may be confused and wondering if a triangle is a polygon and yes, they are. A polygon is any shape with straight lines that don't intersect.
I think its an equilateral triangle, if my geomatry is correct.
They could all be the same length, or two of them could be the same, or they could all be different. In any case, when you add them all up, the number you get is called the "perimeter" of the triangle.
