## Can a ray be called SR and RS?

Ray SR can not be called RS because rays only go in one direction is the ray were RS it would be going the opposite direction or ray SR.

## What is a ray angle?

A line that has one defined endpoint is called a ray and extends endlessly in one direction. A ray is named after the endpoint and another point on the ray e.g. Angles can be either straight, right, acute or obtuse. …

## Is an angle a location?

In trigonometry, an angle is drawn in what is called the “standard position”. The vertex of the angle is on the origin, and one side of the angle is fixed and drawn along the positive x-axis (at the 3 o’clock position as shown as BC above)….Angle (Trigonometry)

## Which kind of angle is the largest?

reflex angle

## Which kind of angle is the smallest?

acute

## What are three ways you can name an angle?

There are three ways to name an angle–by its vertex, by the three points of the angle (the middle point must be the vertex), or by a letter or number written within the opening of the angle.

## What is the largest obtuse angle?

An obtuse angle is a type of angle that is always larger than 90° but less than 180°. In other words, it lies between 90° and 180°.

## What type of angle is 180 degrees?

straight angles

## How do you know if a shape has a right angle?

When two straight lines intersect each other at 90˚ or are perpendicular to each other at the intersection, they form the right angle. A right angle is represented by the symbol ∟.

## Can a trapezoid have two 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 rhombus have 4 right angles?

A square has two pairs of parallel sides, four right angles, and all four sides are equal. It is also a rectangle and a parallelogram. A rhombus is defined as a parallelogram with four equal sides. No, because a rhombus does not have to have 4 right angles.

## Can a 30 40 50 Make a right triangle?

Explanation: Pythagoras’s Theorem states that the square of the length of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the lengths of the other two sides. Actually a 30 , 40 , 50 triangle is just a scaled up 3 , 4 , 5 triangle, which is a well known right angled triangle.

## What is the rule for sides 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. Note: This rule must be satisfied for all 3 conditions of the sides.

## Does 4 5 6 represent a Pythagorean triple?

Explanation: For a set of three numbers to be pythagorean, the square of the largest number should be equal to sum of the squares of other two. Hence 4 , 5 and 6 are not pythagorean triple.
