Is equilateral triangle always an isosceles triangle?
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.
What are the kinds of triangle according to their side?
scalene for no equal sides; isosceles for two equal sides and equilateral for all equal sides
Sum of the two sides of a triangle is greater than its?
Its third side.
What is the name of a triangle with two equal sides?
It is an isosceles triangle -- of necessity there are two identical and mirrored angles.If the third side is also equal, it is an equilateral triangle.If there is also a right angle, the other two angles are 45 degrees and it is an isosceles right triangle.
Explain Why the height of a triangle depends on which side you select for the base?
The height of a triangle is the length of the perpendicular dropped to the base (extended if necessary) from the opposite vertex. This depends on which side is the base, unless the triangle is equilateral. For example, if you have a tall skinny isosceles triangle whose equal sides are a mile long and the third side is an inch long, the height is about a mile if you choose the third side as the base. If you choose either of the other two sides as base, the height will be about an inch.
If the sides of an isosceles triangle are 5 and 8 what is the third side?
The third side would be either 5 or 8,as an isosceles triangle has 2 equal sides.
What are the measures of all angles in a triangle if 2 sides equal the third side?
If two sides of a triangle are equal in length to the third side, then the triangle is equilateral, and all angles are 60 degrees.
What is the third side an isosceles triangle?
An isosceles triangle has 3 sides 2 of which are equal in length
What type of triangle has only two sides with equal measures?
An isosceles triangle has two sides with equal measures. The third side can be any length.
If two sides of a triangle equal 45 what does the third equal and what kind of triangle is this?
If two sides of a triangle each have length of 45 units, then the triangle is isosceles,and the third side can have any length less than 90 units.
The congruent sides of an isosceles triangle?
The congruent sides of an isosceles triangle are the two sides that are equal in length. These two sides are opposite the equal angles of the triangle. The third side, called the base, is not equal in length to the other two sides.
What is a triangle that has two sides the same and the therid different?
It is an isosceles triangle that has two equal sides and the third side being different
What relationships exist between the two congruent sides of an isosceles triangle and its base?
The angles where the equal sides meet the third side of the triangle are equal angles.
What is the rule for the triangle in length and width?
A triangle has 3 sides. The sum of any two sides must be larger than or equal to the length of the third side, and the difference of any two sides must be less than or equal to the length of the third side.
What triangle has two equal sides and one longer one?
An isosceles triangle. It is an isosceles triangle even if the third side is shorter.
What does the triangle inequality state?
It says the sum of the lengths of any 2 sides of a triangle must be greater than the third side. Not equal to but GREATER than the third side.
Which triangle cannot exist?
in which the sum of two sides less than or equal to the third side.
