What is isosceles triangle short answer?

In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.

How do you explain an isosceles triangle?

An isosceles triangle therefore has both two equal sides and two equal angles. The name derives from the Greek iso (same) and skelos (leg). A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle.

What is an isosceles triangle 5th grade?

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’.

How do you explain a triangle to a child?

Definition of a Triangle Simply put a triangle is a shape with three sides and three angles. 3 sides. 3 angles. All of the angles add up to 180 degrees.

How do you explain what a triangle is?

A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side.

How do you prove that a triangle is isosceles?

You can prove a triangle is isosceles by finding the amount of right angles in a triangle. A triangle containing 2 right angles is classified as isosceles.

What are the measurements of an isosceles triangle?

An isosceles triangle has congruent base angles, so if one of the base angles measure 54 degrees, then the other base angle does, too. And a triangle measures up to 180 degrees. 180 = x + 2(54) 180 = x + 108.

What are the possible measures for an isosceles triangle?

For any isosceles triangle, the following six line segments coincide: the altitude, a line segment from the apex perpendicular to the base, the angle bisector from the apex to the base, the median from the apex to the midpoint of the base, the perpendicular bisector of the base within the triangle, the segment within the triangle of the unique axis of symmetry of the triangle, and

What are the three angles of an isosceles triangle?

An isosceles triangle with three equal sides is called an equilateral triangle. There are several properties that are true of every isosceles triangle. A side that is not equal to the other sides is called the base of the triangle. The angles formed by the base, and the other two legs are always equal.
