All triangles have 3 interior angles that add up to 180 degrees and are classified according to the size of their angles as follows:-
Right angle triangle: One 90 degree angle and 2 acute angles
Isosceles triangle: Two equal angles and another angle
Equilateral triangle: Three equal angles each measuring 60 degees
Obtuse triangle: One obtuse angle and 2 acute angles
Scalene triangle: Three acute angles of different sizes
What else can I help you with?
What are the classification of triangles?
Equilateral, isosceles, scalene and right angle triangles.
Are the angle measures of similar triangles different?
for two similar triangles , their corresponding angles are equal.
What do you look for if you want to classify a triangle?
Classifying triangles is a great skill to know.Acute Triangles: These are triangles with measures lessthan 90 degrees.Obtuse Triangles: Any triangle with measures greater than 90 Degrees.Right Triangle: Any triangle with a Right Angle (exactly 90 degrees)
What are the shapes that have 3 sides and 3 vertices?
The shapes that have 3 sides and 3 vertices are called triangles. Triangles are classified based on the lengths of their sides and the measures of their angles. The three most common types of triangles are equilateral triangles (all sides and angles are equal), isosceles triangles (two sides and two angles are equal), and scalene triangles (all sides and angles are different).
Is the sum of the measures of the angles of a triangle always 180?
Yes - in the case of triangles in Euclidian geometry. That is, basically triangles in a plane.
How many triangles have the angle measures 30 65 85?
As many as you like but they will all be scalene triangles
If an angle bisector of an isosceles triangle yields two isosceles triangles what were the angle measures of the original triangle?
they would be congruent triangles!
Congruent triangles have the same shape and size because they will always have the same?
Congruent Triangles have the same angles and side length measures
Do acute triangles have any measures greater than ninety degrees?
No only obtuse triangles have a measure over 90 degrees:)
What geometric figures do not have any right angles or angles whose measures are larger than a right angle?
All triangles that are not right triangles.
Is the measures of corresponding angles in similar triangles the same?
No, I learned that in 6th grade
What instrument measures triangles?
The instrument for measuring the angles of a triangle is called a protractor.
