What is the difference between right angle triangle and all other types triangles?
right angle triangles have a 90˙ angle as one of their angles. All triangles' angles have to add up to 180˙, so the total of the remaining 2 angles has to be 90˙. Other regular triangles are non-specific, their angles just have to add up to 180˙ total.
Can a trapezoids obtuse triangles?
Yes a trapezoid can have 2 obtuse angles and 2 acute angles whereas its 4 interior angles add up to 360 degrees.
Use geometry words to describe how diagonals of quadrilaterals make triangles?
All triangles have 3 interior angles that add up to 180 degrees and the 4 interior angles of a quadrilateral add up to 360 degrees but if 2 of its vertices are joined by a diagonal this marks out 2 interior triangles each having 3 interior angles adding to 180 degrees.
How many triangle doese it take to make a rhombus?
2 triangles make up a rhombus which has 4 interior angles adding to 360 degrees and a triangles has 3 interior angles add up to 180 degrees. Therefore: 360/180 = 2 triangles
What do the angles in two triangles add up?
That's simple! Just times 180, the amount that the three angles in ONE triangle have to add up to, by 2 and you've got the answer. (360)
Can scalene triangles be acute or obtuse?
A scalene triangle can have 1 obtuse angle and 2 different acute angles or it can have 3 different acute angles providing that the 3 angles in both scalene triangles add up to 180 degrees.
Do triangles have any obtuse angles?
Yes a triangle can have 1 obtuse angle and 2 acute angles. The 3 interior angles of any triangle add up to 180 degrees.
Classification of triangles according to the interior angles?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees:- Right angle triangle has a 90 degree angle and 2 acute angles Scalene triangle has 3 different acute angles Obtuse triangle has 1 obtuse angle and 2 different acute angles Isosceles triangle has 2 equal angles and a 3rd angle that all add up to 180 degrees Equilateral triangle has 3 equal 60 degree 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
How many degrees does a supplementary angle add up to?
Supplementary angles are 2 angles that add up to 180°. Complementary angles are 2 angles that add up to 90°.
Why do triangles angles add up to 180 instead of 270?
Because of the formula: (n-2)*180 = total sum of interior angles where n is the number of sides of the polygon.
What is the similarities between triangles?
They each have 3 interior angles that add up to 180 degrees They each have 3 exterior angles that add up to 360 degrees They each have 3 sides They are 2 dimensional shapes They have perimeters They have areas
