Can a person be abstruse?

Can a person be abstruse?

Abstruse is used to describe things that aren’t easily accessible to the lay reader or average person. Specifically, it suggests the use of language or other material that suits the advanced levels of a subject of which the rest of us might have only an elementary understanding.

Does obtuse mean big?

An obtuse angle is a type of angle that is always larger than 90° but less than 180°. In the given figure, ∠XYZ shows an obtuse angle.

What is another word for obtuse?

SYNONYMS FOR obtuse 1 unfeeling, tactless, insensitive; blind, imperceptive, unobservant; gauche, boorish; slow, dim.

What is the opposite of obtuse?

What is the definition for obtuse?

What is the definition of obtuse triangle?

An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees.

Why can’t a right triangle have an obtuse angle?

When an angle of a triangle is 90 degrees, the triangle cannot have an obtuse angle. The other two must each be less than 90 degrees (90 deg + 89 deg + 1 deg = 180 deg). It therefore follows that they must both be less than 90 degrees and so must both be acute.

Can a triangle be obtuse and right?

No, a triangle cannot have an obtuse and a right angle.

Why is it called an obtuse angle?

Angles larger than a right angle and smaller than a straight angle (between 90° and 180°) are called obtuse angles (“obtuse” meaning “blunt”). Angles larger than a straight angle but less than 1 turn (between 180° and 360°) are called reflex angles.

Is 180 degrees an obtuse angle?

Angles between 0 and 90 degrees (0°< θ <90°) are called acute angles. Angles between 90 and 180 degrees (90°< θ <180°) are known as obtuse angles. Angles that are 360 degrees (θ = 360°) are full turn.

What is a real life example of an obtuse angle?

Obtuse angles are seen on most house rooftops, as the two roof surfaces slope down from it. 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.

Why are there 90 degrees in a right angle?

In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.

Why is it called a right angle and not a left angle?

I mean why isn’t called a left angle. The term right in right angle comes from the meaning of right as proper, or in accordance to justice or equality. It comes from the way a right angle was originally defined. When two straight lines intersect they form two angles.

How do you identify a right angle?

A vertical and a horizontal line make most common right angles. However, diagonal lines intersecting each other also form right angles. If you draw the diagonals of a square, a rhombus or a kite, the angle at the intersection is 90 degrees and is, therefore, a right angle.

Can a trapezoid have 2 right angles?

A right trapezoid (also called right-angled trapezoid) has two adjacent right angles. An acute trapezoid has two adjacent acute angles on its longer base edge, while an obtuse trapezoid has one acute and one obtuse angle on each base.

Does a trapezoid have 4 congruent sides?

A square can be defined as a rhombus which is also a rectangle – in other words, a parallelogram with four congruent sides and four right angles. A trapezoid is a quadrilateral with exactly one pair of parallel sides.

Can a trapezium have 4 right angles?

A trapezium cannot have four right angles.

Which shape has most right angles?

Rectangle
