How many sides does a scalene obtuse triangle have?
three sides
A scalene triangle has three sides. In order for any shape to be a triangle, it must have three sides and three angles.
Does a obtuse scalene triangle have equal sides?
An obtuse triangle has three different angles, with one angle greater than 90°. None of its sides are equal in length.
How do you find the length of the sides of an obtuse triangle?
You can calculate an obtuse triangle using the lengths of the triangle’s sides. Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together. For example, if the lengths of the sides measure 3 and 2, then squaring them would result in 9 and 4.
How do you find the sides of a scalene triangle?
Once these measurements are mentioned, we can use the las of cosines to find out the missing side of a scalene triangle. The formula used is: The law of cosines says c2 = a2 + b2 – 2ab cos(c), where c is the angle opposite to the third side.
What is a obtuse scalene triangle?
In geometry, an obtuse scalene triangle can be defined as a triangle whose one of the angles measures greater than 90 degrees but less than 180 degrees and the other two angles are less than 90 degrees. All three sides and angles are different in measurement.
What is a triangle with only 2 equal sides called?
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 the measurement of an obtuse triangle?
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°.
What theorems apply to a obtuse scalene triangle?
The scalene inequality theorem states that in such a triangle, the angle facing the larger side has a measure larger than the angle facing the smaller side.
What are the measurements of an obtuse angle?
Obtuse angles measure more than 90 degrees.
What is the rule for the third side of a triangle?
The Formula The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. Note: This rule must be satisfied for all 3 conditions of the sides.
What is a triangle with an obtuse angle called?
An obtuse triangle is a type of triangle where one of the vertex angles is greater than 90° Hence, they are called obtuse-angled triangle or simply obtuse triangle. An obtuse-angled triangle can be scalene or isosceles, but never equilateral. The perimeter of an obtuse triangle is the sum of the measures of all its sides.
How do you find the angle of an obtuse triangle?
Since every triangle has a measurement of 180 degrees, a triangle can only have one obtuse angle. You can calculate an obtuse triangle using the lengths of the triangle’s sides. Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together.
How many obtuse angles does an obtuse triangle have?
An obtuse triangle is one with one obtuse angle (greater than 90°) and two acute angles. Since a triangle’s angles must sum to 180°, no triangle can have more than one obtuse angle.
What are the properties of an obtuse triangle?
Properties of Obtuse Triangles The longest side of an obtuse triangle is the one opposite the obtuse angle vertex. An obtuse triangle may be either isosceles (two equal sides and two equal angles) or scalene (no equal sides or angles). An obtuse triangle has only one inscribed square.
