The longest side of a right- angled triangle is called the hypotenuse.
What is the longest side of a scalene triangle?
The scalene triangle is a type of triangle with sides of three different lengths and angles of three different measurements. In every scalene triangle, the shortest side is opposite the smallest angle and the longest side is opposite the largest angle.
What are the sides of a scalene triangle?
A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures. Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent.
What is the longest side of a triangle called?
We define the side of the triangle opposite from the right angle to be the hypotenuse, h. It is the longest side of the three sides of the right triangle. The word “hypotenuse” comes from two Greek words meaning “to stretch”, since this is the longest side.
Do all sides of a scalene triangle have the same length?
Sometimes called an irregular triangle. Scalene triangles are triangles where each side is a different length. … The interior angles of a scalene triangle are always all different. The converse of this is also true – If all three angles are different, then the triangle is scalene, and all the sides are different lengths.
Which is the shortest side in right angle triangle?
In any triangle, the longest side is opposite the largest angle, and the shortest side is opposite the smallest angle. Thus, in a right triangle, the hypotenuse is always the longest side.
What do 3 sides of a triangle equal?
An equilateral triangle has three equal length sides and three equal inside angles. Each of the angles measures 60º.
What is a scalene triangle look like?
A scalene triangle has three sides of different lengths. No congruent sides. Note: The angles in a scalene triangle are also of different measures. An isosceles triangle has two congruent sides.
Is a scalene a triangle?
All angles of a scalene triangle are unequal. A scalene triangle has no line of symmetry. The angle opposite to the longest side would be the greatest angle and vice versa. All sides of the given scalene triangle are unequal.
How many sides are equal in a scalene triangle?
Comparison-Scalene, Isosceles and Equilateral
|Scalene Triangle||Isosceles Triangle||Equilateral Triangle|
|All three sides are unequal||Any two sides are equal||All three sides are equal|
|All three angles are different||Angles opposite to equal sides are equal||All three angles equal to 60 degrees|
What is the rule for finding the missing side of a triangle?
Finding the missing side of a right triangle is a pretty simple matter if two sides are known. One of the more famous mathematical formulas is a2+b2=c2 a 2 + b 2 = c 2 , which is known as the Pythagorean Theorem.
Does 9 12 15 make a right triangle?
The three sides 9 in, 12 in, and 15 in do represent a right triangle. Since the square of the hypotenuse is equal to the sum of the squares of the other two sides, this is a right triangle.
What is the shortest side of a triangle?
The shortest side is the one opposite the smallest angle. If the angle you already know is the shortest one, then the shortest side is opposite it.
How do you classify a triangle by its side lengths?
Classifying Triangles by Sides
- scalene triangle-a triangle with no congruent sides.
- isosceles triangle-a triangle with at least 2 congruent sides (i.e. 2 or 3 congruent sides)
- equilateral triangle-a triangle with exactly 3 congruent sides.
- NOTE: Congruent sides means that the sides have the same length or measure.
How do you classify a triangle by its length?
Classifying a triangle is as simple as comparing the sides. If all three sides have the same length then it is an EQUILATERAL triangle, if only two sides have the same length then it is an ISOSCELES triangle and if there are no sides that have the same length then it is a SCALENE triangle.
What triangle has two sides?
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.
