Which do you use when parallel lines form similar triangles?
Triangles do not have parallel lines but as right angles triangles they do have perpendicular lines that meet at 90 degrees.
Are squares and triangles polygons?
Yes they have straight lines no curves and angles.
Can a trapezium be divided into 3 triangles using 2 lines?
Yes, draw the lines from the obtuse angles to the center of the line opposite from it.
What is triginometry?
It started off as a study of triangles and is a study of straight lines and angles, as well as relationships between them.
Do Similar triangles have proportional angles?
Similar triangles don't just have proportional angles, they have IDENTICAL angles!
Which do you use when parallel lines form similar triangles?
Triangles do not have parallel lines but as right angles triangles they do have perpendicular lines that meet at 90 degrees.
What do triangles have?
two acute angles and three lines
Are squares and triangles polygons?
Yes they have straight lines no curves and angles.
If two lines are cut by a transversal are the corresponding angles congruent?
No. Angles are not congruent. (Triangles may be congruent.)
Why are triangles sometimes similar?
Because they have the same length of lines and same angles.
Can a trapezium be divided into 3 triangles using 2 lines?
Yes, draw the lines from the obtuse angles to the center of the line opposite from it.

What is the definition for the word trigometry?
I believe you were going for Trigonometry. * (from the Greek trigonon = three angles and metro = measure) is a part of elementary mathematics dealing with angles, triangles. * the part of math to do with the sides and angles of triangles. Used in navigating, surveying and engineering. * Study of the Relationships of Lines & Angles in the Triangle.
Do Similar triangles have proportional angles?
Similar triangles don't just have proportional angles, they have IDENTICAL angles!
What are a score or more facts relevant to triangles?
They are as follows:- 1 Triangles are 2 dimensional polygon shapes 2 Triangles have 3 sides 3 Triangles may have acute angles greater than 0 but less than 90 degrees 4 Triangles may have right angles which are 90 degrees 5 Triangles may have obtuse angles greater than 90 but less than 180 degrees 6 Triangles have 3 interior angles that add up to 180 degrees 7 Triangles have 3 exterior angles that add up to 360 degrees 8 Triangles can be scalene which have 3 acute angles 9 Triangles can be right angled with a 90 degree angle and 2 acute angles 10 Triangles can be obtuse with 1 obtuse angle and 2 acute angles 11 Triangles can be isosceles with 2 equal angles and another angle 12 Triangles can be equilateral with 3 equal angles of 60 degrees 13 Triangles have no diagonals 14 Triangles will tessellate 15 Triangles have lines of symmetry when they are isosceles or equilateral 16 Triangles have perimeters which is the sum of their 3 sides 17 Triangles have areas which is 0.5*base*altitude 18 Triangles can be used with Pythagoras' theorem if they are right angled 19 Triangles can be used in conjunction with trigonometry 20 Triangles are found in all other polygons 21 Triangles and their properties were known by the ancient Greeks 22 Triangles can be made into musical instruments
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
What are geometric triangles?
a shape or figure with no bent or curvy lines only striaght lines and has three sides which the sum of the angles must equal 180 degress
