What is an example of obtuse?
The definition of obtuse is someone who is slow to understand things. An example of obtuse is someone who listens to a joke but doesn’t understand the punchline. The definition of obtuse is something that isn’t sharp. An example of obtuse is a child’s pair of scissors.
What items are obtuse angles?
Other real world examples of an obtuse angle include the angle between the screen and the base of an opened laptop, a hockey stick, an accordion hand fan and between the wings of a boomerang. In general, obtuse angles are observed whenever two sides, arms or surfaces deviate widely.
What shapes are obtuse angles?
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 is an example of a obtuse triangle?
If one angle is greater than 90° and the other two angles are lesser along with their sum being lesser than 90°, we can say that the triangle is an obtuse triangle. For example, ΔABC has these angle measures ∠A = 120°, ∠A = 40°, ∠A = 20°. This triangle is an obtuse triangle because ∠A = 120°.
What are the characteristics of a obtuse triangle?
Obtuse Triangle Definition An obtuse triangle is one that has an angle greater than 90°. Because all the angles in a triangle add up to 180°, the other two angles have to be acute (less than 90°). It’s impossible for a triangle to have more than one obtuse angle.
What is the meaning of obtuse triangle?
An obtuse triangle is a triangle in which one of the angles is an obtuse angle. (Obviously, only a single angle in a triangle can be obtuse or it wouldn’t be a triangle.) A triangle must be either obtuse, acute, or right.
What are types of triangle?
What are the types of triangle?
- The sum of angles in any triangle is 180°.
- An equilateral triangle has three equal sides and angles.
- An isosceles triangle can be drawn in many different ways.
- A right-angled triangle has one 90° angle.
What is straight triangle?
A straight line triangle representation (SLTR) of a planar graph is a straight line drawing such that all the faces including the outer face have triangular shape. The characterization is based on flat angle assignments, i.e., selections of angles of the graph that have size~\pi in the representation.
What are the 3 sides of a triangle called?
In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle.
What side is a in a triangle?
In any right-angled triangle, ABC, the side opposite the right-angle is called the hypotenuse. Here we use the convention that the side opposite angle A is labelled a. The side opposite B is labelled b and the side opposite C is labelled c.
What is the name of Triangle?
“There are four types of triangle: equilateral, isosceles, scalene and right-angled.”
What is triangle and example?
The definition of a triangle is a shape with three angles and three sides. An example of something in the shape of a triangle is a piece of pizza. Any three-sided or three-cornered figure, area, object, part, etc.
What are the six parts of a triangle?

What is Triangle Class 9?
You know that a closed figure formed by three intersecting lines is called a triangle. (‘Tri’ means ‘three’). A triangle has three sides, three angles and three vertices.
