What is obtuse Behaviour?
The adjective obtuse is good for describing someone slow on the uptake: "Don't be so obtuse: get with the program!" The adjective obtuse literally means "rounded" or "blunt," but when it's used for a person, it means "not quick or alert in perception" — in other words, not the sharpest tool in the shed.
What does a obtuse triangle look like?
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°. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees.
What are the sides of an acute triangle?
Properties of Acute Triangles An equilateral triangle has three sides of equal length and three equal angles of 60°. An acute triangle has three inscribed squares. Each square coincides with a part of a triangle side. The other two vertices of a square are on the two remaining sides of the acute triangle.
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.
What are the rules of a right triangle?
The Pythagorean theorem states that: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).
What are the side lengths of a 30 60 90?
A 30-60-90 triangle is a special right triangle whose angles are 30º, 60º, and 90º. The triangle is special because its side lengths are always in the ratio of 1: √3:2. Any triangle of the form 30-60-90 can be solved without applying long-step methods such as the Pythagorean Theorem and trigonometric functions.
What are the possible side lengths of a triangle?
SOLUTION: The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Since, 6 + 14 > 10, 6 + 10 > 14, and 10 + 14 > 6, you can form a triangle with side lengths 6 m, 14 m, 10 m.
What is the rule for the third side of a triangle?
Triangle Inequality Theorem. The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
How do you find the third side of a triangle if two sides are known?
Just like the Law of Sines, the Law of Cosines works for any triangle, not just right triangles. In particular, the Law of Cosines can be used to find the length of the third side of a triangle when you know the length of two sides and the angle in between.
How do you find the length of the third side of a triangle?
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.
