"Isosceles" is made from the Greek roots "isos" (equal) and "skelos" (leg). The same word is used, for instance, for isosceles trapezoids, trapezoids with two equal sides, and for isosceles sets, sets of points every three of which form an isosceles triangle.
An isosceles triangle has two equal sides (or three, technically) and two equal angles (or three, technically). The equal sides are called legs, and the third side is the base. The angle between the two legs is called the vertex angle. The above figure shows two isosceles triangles.
In Euclidean geometry, an isosceles trapezoid (isosceles trapezium in British English) is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. Alternatively, it can be defined as a trapezoid in which both legs and both base angles are of the same measure.

An isosceles right triangle is an isosceles triangle and a right triangle. This means that it has two congruent sides and one right angle. Therefore, the two congruent sides must be the legs. Therefore, we only need one of the three lengths to determine the other two lengths of the sides of an isosceles right triangle.
By definition, an acute isosceles triangle will have at least two sides (and at least two corresponding angles) that are congruent, and no angle will be greater than . Addtionally, like all triangles, the three angles will sum to .
Answer. The plural form of isosceles triangle is isosceles triangles.
We know that an isosceles triangel has two equal sides and thus two equal angles opposite those equal sides. Because there is one obtuse angle of 112 degrees we automatically know that this angle is the vertex. If you sum any triangle's interior angles, you always get 180 degrees.
An isosceles trapezoid has one pair of parallel sides and another, different pair of congruent sides. They look like this: The trapezoid has one line of symmetry - the cyan line. The green angles are congruent, and the orange angles are congruent.
We can see that the three angles in an isosceles triangle add up to 180°.

A scalene triangle is a triangle that has three unequal sides, such as those illustrated above. SEE ALSO: Acute Triangle, Equilateral Triangle, Isosceles Triangle, Obtuse Triangle, Triangle.
Scalene sentence exampleA scalene triangle abc might also be employed, or a tetrahedron. 25) that he perfected the things relating to the scalene triangle and the theory of lines.
In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
A triangle with two sides of equal length is an isosceles triangle. The two equal sides of an isosceles triangle are known as 'legs' whereas the third or unequal side is known as the 'base'.
An isosceles triangle is a triangle with two equal or congruent sides.
No, an isosceles triangle does not always have a right angle. The only properties that a triangle must satisfy to be an isosceles triangle is that it
Answer. We can find the height by splitting the isosceles triangle into two right-angled triangles and then applying Pythagoras' Theorem to one of them. h = 13.20 ( t o 2 d . p . )
Every triangle has 180 degrees. An isosceles triangle has one vertex angle and two congruent base angles. Thus the vertex angle is 38 and the base angle is 71 and their sum is 109.
In an isosceles triangle, the base angles have the same degree measure and are, as a result, equal (congruent). Similarly, if two angles of a triangle have equal measure, then the sides opposite those angles are the same length. The easiest way to define an isosceles triangle is that it has two equal sides.
