What do you called an angles measure 90 degree?
A right angle.
What are two lines that intersect so that each angle they form measure 90 degrees?
A pair of lines that intersect each other perfectly form 90 degree angles are perpendicular. Anything else is just intersecting lines
If two straight lines intersect and one angle is 30 degree's what are the other three vertical angles?
When two nonvertical straight lines intersect they form two congruent pair of nonadjacent angles, which are called the vertical angles (or vertical opposite angles). So that one of the three vertical angles is 30 degrees, and the other two angles have a measure of 150 degrees each, since they are adjacent to a 30 degrees angle.
Is a 25 degree angle is congruent to a 25 degree angle?
Yes. Angles are congruent if they have the same measure.
How do you justify 90 degree angle?
Perpendicular lines for example intersect each other at right angles which is 90 degrees
What is called lines that intersect to from 90 degree angles?
A right angle
Is a 200 degree angle an obtuse angle?
No, a 200 degree angle is a reflex angle. Reflex angles are angles that measure more than 180 degrees.
Are intersecting lines alway perpendicular?
Form right angles
What does a right triangle angles measure?
They have one 90 degree angle and two 45 degree angles
How do you use a protractor to measure angles?
put the protractor on the vertex and look up at the degree's and look belowacute angle =has a measure between 0 degree's and 90 degree'sright angle =has a measure of 90 degree'sobtuse angle = has a measure between 90 degree's and 180 degree'sstraight angle = has a measure of 180 degree'sthat's how you use a protractor to measure angles.

Is a 25 degree angle is congruent to a 25 degree angle?
Yes. Angles are congruent if they have the same measure.
What is the measure of the complementary angle to a 31 degrees angle?
Complementary angles consist of 2 angles that add up to 90 degrees; so the complimentary angle to a 31 degree angle is a 59 degree angle.
If the measure of angle DAB is 50 degrees and the measure of angle DAC is 20 degree what is measure of CAB?
If that is the angles of a triangle then the 3rd angle is 110 degrees
How do you justify 90 degree angle?
Perpendicular lines for example intersect each other at right angles which is 90 degrees
