**What is a full circle angle called?**

The Full Circle A Full Circle is 360° Half a circle is 180° (called a Straight Angle) Quarter of a circle is 90° (called a Right Angle)

**What is a standard position angle?**

: the position of an angle with its vertex at the origin of a rectangular-coordinate system and its initial side coinciding with the positive x-axis.

### What type of angle is 72 degrees?

acute angle-an angle between 0 and 90 degrees. right angle-an 90 degree angle. obtuse angle-an angle between 90 and 180 degrees.

**What is a 40 angle?**

Classification of angles on the basis of their degree measures are given below: Acute Angle: An angle whose measure is more than 0° but less than 90° is called an acute angle. Angles having magnitudes 30°, 40°, 60° are all acute angles.

**What is an angle for Class 4?**

An angle is formed when two rays are joined together at a common point. The common point here is called node or vertex and the two rays are called arms of the angle. The angle is represented by the symbol ‘∠’. The word angle came from the Latin word “Angulus”.

## What angle is 1 o clock?

So the angle between the hands of a clock at 1 o’clock is 30° . Note: It doesn’t matter whether we are talking about 1 am or 1 pm, the answer is exactly the same for both. The angle between the hands at 1 o’clock could also be given as the reflex angle 330°, but we will always give the smaller (acute or obtuse) angle.

**How to make a triangle with one angle and one leg?**

Right triangle given one angle and one leg (LA) This page shows how to construct a right triangle that has one leg (L) and one angle (A) given. It works in three steps: Copy the angle A. (See Copying an angle) Copy the length of the given leg onto the bottom angle leg (See Copying a segment) Erect a perpendicular from the end of the leg.

**How to construct an angle congruent to a given angle?**

How to Construct an Angle Congruent to a Given Angle. 1. Use the straight edge to draw a ray. Begin by marking a point where you want to place your new angle. Label the point M. Align your straight edge 2. Set the compass to any comfortable length. You will need to mark an arc on the original

### How do you construct an angle from a line?

Place an arrow point at the end of the line you drew and label it N. You have just drawn Ray MN. This will be the base of the angle you construct. Set the compass to any comfortable length.
