How many of vertical angles in a triangle?
Three
What is a counter example for the statement congruent angles are always vertical angles?
Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.
How do you determine a triangle is an obtuse triangle?
If one of its angles are greater than 90 degrees, and the other 2 angles are acute
How do you determine if a triangle is a right angle?
If one of the angles in a triangle is exactly 90 degrees, then it is a right-angle triangle.
How do you determine that the triangle is a right triangle through the 3 vertices?
If one of the three interior angles is 90 degrees then it is a right triangle.
How do we determine that the isosceles triangle is an isosceles triangle?
2 interior angles are equal and 2 sides are of equal length.
What is the difference between vertical angles and congruent angles?
not all congruent angles are vertical angles. Vertical angles must share a vertex.
Determine the measure of the missing angle in the triangle below the sum of the three angles in a triangle is 180 degree?
37 degree
How do you determine that the isosceles triangle is an isosceles right triangle?
The three interior angles measure 45, 45 and 90 degrees.
Are vertical angles congruent or supplementary angles?
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
If two angles are vertical then what are they?
If two angles are vertical then they are congruent.
Are all the sides of a right triangle perpendicular?
If you have a triangle then one of the sides cannot be perpendicular to the other two. It is true for a square but it is impossible with a triangle. Definition of perpendicular: Being at right angles to the horizontal; vertical.
