There are two triangles with sides 9 x 12 x 15 meters. Each of the two triangles is inversely congruent (mirror image) to the other.
Only one angle is formed by two sides of a triangle. It can be anything less than 180 degrees.
The triangle is the only one.
A triangle with 3 equal sides is an equilateral triangle. A triangle with 2 equal sides is an isosceles triangle. There is no such thing as a triangle with ONE equal side. Equal to what? If you wish to stretch it and say each side is (equal to itself only ) not equal to any others it is a scalene triangle.
A right triangle
A isosceles triangle has 2 sides that are the same length and a scalene triangle has no sides that are the same.
A triangle has no parallel sides but a right angle triangle has perpendicular sides that meet at 90 degrees.
Thats already a triangle if it three sides.
You need the measures of two sides and for the triangle to be a right triangle to figure out the third side.
No, only right triangle has one hypothenuse and two sides.
One more because an equilateral triangle has 3 equal sides whereas a right isosceles triangle has only 2 equal sides.
One more because an equilateral triangle has 3 equal sides whereas a right isosceles triangle has only 2 equal sides.
If an isosceles triangle is defined as one which has two sides (or angles) equal, then YES. But if an isosceles triangle is defined as one which has two sides (or angles) equal, and the third side (angle) different, then NO.
Only one angle is formed by two sides of a triangle. It can be anything less than 180 degrees.
A rectangle has four sides whereas a right angle triangle has only three sides.
The triangle is the only one.
1 triangle = 3 sides, no matter what kind of triangle it is 5 triangles = 3 sides each = 15 sides
An isosceles triangle has 2 equal sides and 1 side different in length
