OGT Math Measurement D Triangles

QuestionAnswer
The sum of the measure of the angles of a triangle always equals ____ degrees 180
If angle A equals 50 degrees and B equals 55, what is the value of angle C? 75 because 50 + 55 + C = 180
Equilateral Triangle All three sides of equal length.
Isosceles Triangle At least two sides of equal length.
Acute Triangle All angles are acute (less than 90degrees)
Obtuse Triangle One obtuse angle (greater than 90degrees)
Right Triangle At least one right angle
In a right triangle if one acute angel is 40 degrees, how much is the other? 50
Each angle in an equilateral triangle is ___ degrees 60
A triangle with no congruent sides is called ____ scalene
the side across from a right angle HYPOTENUSE
If a triangle has 2 congruent sides then it has ___ 2 congruent angles
If a triangle has 3 congruent angles then it has ___ 3 congruent sides
True or False If a triangle is obtuse then it will have an angle sum of 180 True - all triangles have an angle sum of 180
The sum of the measure of the angles of a triangle always equals ___ degrees 180
A ____ has At least two sides of equal length Isosceles Triangle

The triangle ABC is an equilateral triangle. What is the measure of angle A? 60 degrees
In a right triangle, if one acute angle equals 64ᅡᄚ, what is the value of the other? 26 degrees
In a triangle, A = 60ᅡᄚ, B = 60ᅡᄚ, and Z = 10 cm. What is the length of side X? 10 cm (they are all the same length
If a triangle has two equal sides then it also has ___ 2 equal angles
If angle A = C = 30 degrees. What type of triangle is it? Isosceles (it has two equal angles so it must have 2 equal sides)
