Why cant triangles have reflex angles?

Anonymous

∙ 14y ago

Updated: 11/2/2022

The three interior angles of every triangle add up to 180 degrees,

so none of them can be greater than 180 degrees.

What traingle has a reflex angle?

No triangle can ever have a reflex angle inside it.

What is the difference between scalene obtuse and acute triangles?

There are two questions that have been mixed up here. There are three "main" types of angle: Acute, Obtuse and Reflex. Acute angles are from 1 to 89 degrees, Obtuse angles from 91 to 179 and Reflex angles anything over 181 degrees. An angle of 90 degrees is a right angle, and an angle of 180 degrees is just a line. There are three types of triangle: Equilateral, Isosceles and Scalene. Equilateral triangles have all three sides the same length (and the angles are all 60 degrees), isosceles triangles have two equal-length sides of length and two equal angles, and scalene triangles have all three sides different lengths, and all three angles are different.

What are the kinds of angle and triangle?

Types of angles: acute, right angle, obtuse and reflex Types of triangles: equilateral, isoceles, right angle triangle and scalene

Do Similar triangles have proportional angles?

Similar triangles don't just have proportional angles, they have IDENTICAL angles!

How many triangles does a 1002 sided polygon have?

Any n-sided polygon (n being any integer) will always have a minimum of n-2 triangles inside the shape, assuming that the polygon is regular with no reflex angles.

What traingle has a reflex angle?

No triangle can ever have a reflex angle inside it.

Is it possible to have a quadrilateral with 2 reflex angles?

No. All quadrilaterals can be made from joining two triangles, hence they all have interior angles that sum to 360 degrees. Reflex angles are greater than 180 degrees so two reflex angles would be too big!

Why cant a triangle have four acute angles?

because triangles only have 3 angles that add up to 180

Why cant a triangle have a reflex angle?

The three interior angles in a triangle must add up to 180o, and a reflex angle is one that is bigger than 180o. This makes it impossible for a triangle to have any interior reflex angles.

Why can't triangles have a reflex angle?

A reflex angle is between 180Â° and 360Â°. The sum of the 3 angles in a triangle is 180Â°, so the largest possible angle in a triangle is slightly less than 180Â°

How many diagonals does a irregular hexagon?

It varies. If it has reflex angles, then it varies, depending on the number of reflex angles and their location in relation to each other. Otherwise (if it has no reflex angles) then it has 4 diagonals.

Why cant there be a obtuse angle in a right triagle?

A triangles angles must add up to 180 degrees, no more or less
