What is a triangle called if all the angles and all sides are equal?
An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.
When all angles are equal and all sides are equal?
Equilateral – all the sides are equal lengths, and all the internal angles are 60°.
What is it called when all angles are equal?
Congruent angles are the angles that have equal measure. So all the angles that have equal measure will be called congruent angles. They are seen everywhere, for example, in equilateral triangles, isosceles triangles, or when a transversal intersects two parallel lines.
What are the 3 types of triangles?
Let’s start with the three types of triangles that are categorized by the measure of their largest angle. These are the acute, right, and obtuse triangles.
What does isosceles triangle mean?
: a triangle in which two sides have the same length.
What is the meaning of acute angle triangle?
An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.
What is quadrilateral triangle?
Introduction. A triangle is a simple closed curve or polygon which is created by three line-segments. On the other hand, in terms of Euclidean plane geometry, a polygon having four edges (or sides) together with four vertices is called a quadrilateral.
What is isosceles acute triangle?
In geometry, an isosceles triangle is a triangle that has two sides of equal length. The two angles opposite the legs are equal and are always acute, so the classification of the triangle as acute, right, or obtuse depends only on the angle between its two legs.
What are the sides of a triangle called?
The side opposite to the right angle is the hypotenuse, the longest side of the triangle. The other two sides are called the legs or catheti (singular: cathetus) of the triangle.
Do all triangles have 3 equal sides and 3 angles?
A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal. The triangles are therefore perspective triangles.
What are the three sides of a triangle called?
Hypotenuse, opposite, and adjacent.
What is a socialist triangle?
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.
What is a triangle that has all sides equal called?
A triangle that has all its sides equal in dimension and each angle measure up to 60 degrees, is called an equilateral triangle. What type of polygon is an equilateral triangle? An equilateral triangle is a regular polygon or a regular triangle. What is the different name of triangles based on sides?
What are the angles of an equilateral triangle equal to?
Also, the three angles of the equilateral triangle are congruent and equal to 60 degrees. Suppose, ABC is an equilateral triangle, then, as per the definition; AB = BC = AC, where AB, BC and AC are the sides of the equilateral triangle.
Can two triangles have the same sides but different angles?
A triangle can have all sides same or all sides different. Similarly, a triangle can either have all angles same or all angles different. The angles can be less than, more than or equal to 90degrees. Two triangles having the same angles but different length of sides are called similar triangles.
Is the equilateral triangle a regular polygon with three sides?
All three sides are equal. All three angles are congruent and are equal to 60 degrees. It is a regular polygon with three sides. The perpendicular drawn from vertex of the equilateral triangle to the opposite side bisects it into equal halves.
