Question
Answer
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  
🗑
A ____ has All three sides of equal length.   Equilateral Triangle  
🗑
A ____ has All angles are acute (less than 90ᅡᄚ)   Acute Triangle  
🗑
A(n) ____ has One obtuse angle (greater than 90ᅡᄚ)   Obtuse Triangle  
🗑
A Right Triangle has at least one angle measuring ____   90 degrees  
🗑
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)  
🗑
If angle A equals 50ᅡᄚ and B equals 55ᅡᄚ, what is the value of the third angle of the triangle?   75 degrees (the total is 180)  
🗑
In a triangle, what is the value of angle A + angle B + angle C?   180  
🗑
An isosceles triangle is a triangle with at least two _____ of equal length and at least two angles of equal measure   sides  
🗑
