A:### Quick Answer

Construct a 135-degree angle by first constructing a 90-degree angle. Construct an angle bisector for one side of the right angle. The angle addition theorem allows addition of the resulting 90-degree and 45-degree angles to create the required angle. The construction takes a few minutes using ruler and compass.

Know More**Draw a line segment**Use the ruler to draw a line-segment. Label the line-segment with X and Y at its endpoints

**Construct the 90-degree angle**Set the compass to a convenient length. Place the point of the compass on point x and draw an arc that cuts through line-segment XY at a new point, P. Keep the point of the compass on point X and draw an arc above the line. Move the point of the compass to point P and draw an arc intersecting the first arc. Label the intersecting point as Z. Connect X to Z and extend the line to create a right angle.

**Extend line-segment XY to T**Use the ruler to extend the line segment the opposite direction from Y. Label the new endpoint.

**Construct the angle-bisector**Place the point of the compass on point X and draw arcs to intersect line-segments XY and XT. Label these intersections as A and B. Place the point of the compass at point A. Draw a new arc near the center of angle TXZ. Repeat with point B. Label this intersection point F. Draw a line segment from X to F and extend the line. Angle FXY is the required 135-degree angle.

## What is the common end point of the sides of an angle?

A:

Full Answer >**The common endpoint of the sides of an angle is called a vertex.**For example, triangles have three vertices, while squares have four. These common endpoints are often colloquially called corner points, though this may result in confusing them with angles.Filed Under: - Q:
## How do you read a protractor?

A:A protractor is an inexpensive math tool used to measure the sharpness of an angle in a geometric shape. Reading a protractor is fairly simple.

## What is acute angle?

A:

Full Answer >**An acute angle is any angle with a measure of less than 90 degrees.**Obtuse angles measure more than 90 degrees, and right angles measure exactly 90 degrees.Filed Under: - Q:
## What is angular uncomformity?

A:

Full Answer >**An angular unconformity is a geological phenomenon where an older layer of rock sits directly beneath a much younger layer of rock because the older layer was forced up at an angle, eroded, and younger rock deposited on top of it.**An angular unconformity only stays constant for a relatively short distance into a rock face. Digging horizontally into the older rock reveals younger angled layers.Filed Under:
