Are alternative interior angles always acute?
no
What are alternative exterior angles used for in life?
They are found on the transversal line that cuts through parrallel lines
When two lines are cut by transversal if the alternative interior angles are equal in measure then the lines are parallel?
Yes.
Why the measure of exterior angles is equal to the sum of the measures of interior opposite angles?
That is only true of triangles and is a consequence of the parallel postulate. In fact it is an alternative way of stating Euclid's parallel postulate.
What is an alternate interior angle?
Two lines are crossed by one another line called the transversal. The pairs of angles on opposite sides of the transversal but inside the two lines are called alternative interior angles.
What is the angle measure for each of the angles on a regular 50 - gon?
Sum of interior angles of ANY n-sided pentagon is (2n - 4) right angles, so 100 - 4 = 96 right angles ie 8640 degrees and each angle = 8640/50 = 172.8 degrees. Alternative method: Total exterior angles = 360 degrees so each in 50-gon is 360/50 ie 7.2 degrees. Interior angles are therefore 180 - 7.2 ie 172.8 degrees.
What are consecutive angles angles are also called?
Angles angles angles
What are four types of angles?
There are right angles, acute angles, obtuse angles, and straight angles.
What angles form square angles?
90 degree angles.90 degree angles.90 degree angles.90 degree angles.
What are interior and exterior angles?
they are angles that are wierd and dont make angles that are angles to 360 degrees and make non-angles to make angles
What is congurent angles?
congurent angles are angles that have equal angles. Example, if you want to have equal angles, you have to have a shape that has equal sides
What is the importance of angles to shapes and or angles?
Some shapes have angles and so they are important in defining the shapes. And angles are absolutely critical for angles. They are the very essence of their existence: if it were not for angles then there would be no angles.
