All angles less than 90 degrees : acute angled triangle
One angle equal to 90 degrees: right angled triangle
One angle greater than 90 degrees: obtuse angles triangle.
Although the following names derive from the properties of the sides of a triangle, the definitions can also be determined by the properties of a triangle's angles:
All three angles equal (to 60 degrees): equilateral
Two angles equal, but different from the third: isosceles
All three angles different: scalene

What is the measure of angle 3?
Without additional information or context, it is not possible to determine the measure of angle 3. The measure of an angle is typically given in degrees and can vary depending on the specific geometric configuration or problem.
Isosceles triangles equal 180 degrees?
No, isosceles triangles do not have a fixed angle sum. The angles of an isosceles triangle can vary depending on the specific measurements of the triangle. However, any triangle, including an isosceles triangle, will always have angle measures that add up to 180 degrees.
Does a diagonal of a parralelogram divide a parallelogram into two congruent triangles?
Yes, a diagonal of a parallelogram divides it into two congruent triangles. This is because the opposite sides of a parallelogram are parallel and congruent, so the two resulting triangles formed by the diagonal are mirror images of each other and thus congruent.
What is the system of mathematics used for surveying an indirect measurements?
Trigonometry is the branch of mathematics commonly used in surveying for indirect measurements, such as determining distances or heights of objects that are not directly accessible. Trigonometric functions like sine, cosine, and tangent are used to calculate angles and distances based on known measurements and relationships between sides and angles of triangles. This allows surveyors to accurately determine measurements without physically measuring every point.
What divides a parallelogram into two congruent triangles?
The diagonal of a parallelogram divides it into two congruent triangles. This is because the diagonal creates two pairs of congruent triangles by dividing the parallelogram into two equal halves.
Do Similar triangles have proportional angles?
Similar triangles don't just have proportional angles, they have IDENTICAL angles!
What are triangles that have equal corresponding angles?
Isoceles triangles and right triangles have 2 corresponding equal angles three equal corresponding angles are equilateral triangle
Are triangles equilateral?
Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.
How many angles are in 8 triangles?
1 triangle = 3 angles. 8 triangles = 8*3 = 24 angles!
Do triangles have at least one right angle?
Triangles can be classified by their sides or their angles. When classifying them by their angles, triangles are called: acute triangles - all three angles are acute (less than 90º) right triangles - one right angle (90º) and two acute angles obtuse triangles - one obtuse angle (larger than 90º) and two acute angles
How many angles are in four triangles?
1 triangle = 3 angles so 4 triangles = 4 x 3 = 12 angles unless some triangles are within others
Do all triangles have the same sum of their angles?
Yes, all triangles have the sum of their angles as 180 degrees.
How can you classify triangles by their angles?
Triangles may be right triangles equilateral triangles acute or obtuse triangles
How you can prove that the angles of two triangles are equal?
If the angles of two triangles are equal the triangles are similar. AAA If you have three angles on both triangles these must be equal for the triangles to be similar. SAS If you have an angle between two sides and the length of the sides and the angle are the same on both triangles, then the triangles are similar. And SSS If you know the three sides
Why don't triangles have right angles?
Right angled triangles do!
What types of triangles have at least two acute angles?
All triangles need at least two acute angles
Triangle has no equal anles or sides?
Equaliateral Triangles have all three sides and angles (60 degrees)equal Isosceles Triangles have to equal sides and angles Scalene Triangles have no equal sides or angles
