Every triangle have 6 main parts: 3 sides and 3 angles. On a right triangle one of the angles has to be a right angle, meaning it has a 90 degree angle.
A quadrilateral is a 4 sided shape whose 4 interior angles add up to 360 degrees.
Parallelograms: 1.)opposite side of a parallelogram are parallel and you can prove that by finding the slope for both lines. 2.) opposite sides of a parallelogram are congruent 3.) diagonals bisect each other 4.)opposite angles are congruent 5.) consecutive angles are supp. *Remember that alternate interior angles are congruent.
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are graded as follows:- Scalene triangle has 3 different acute angle Right angle triangle has a 90 degree angle and 2 acute angles Obtuse triangle has 1 obtuse angle and 2 acute angles Equilateral triangle has 3 equal sides and 3 equal angles of 60 degrees Isosceles triangle has 2 equal sides and 2 equal base angles
There are right angles, acute angles, obtuse angles, and straight angles.
Complementary angles add up to 90 degrees.
They have equal measure.
-- It has four sides. -- Opposite sides are parallel. -- All interior angles are right angles.
No sides are congruentNo angles are congruent>Insert 3 more characteristics
Their opposite angles are equal
a rectangle has 4 right angles, a parallelogram has 2 acute angles and 2 obtuse angles
A pentagon has five sides and five angles, the only 2-D shape with these characteristics.
They share one side (line segment).
It has right angles that are 90% when it meets or crosses.
It depends you want. For instance, if you were to draw the plus sign then all angles are 90 degrees. There are 2 lines of symmetry. Furthermore, there are 2 straight angles. To conclude there are many characteristics.
All its sides are unequal, all its angles are unequal.
sides are congruent angles are congruent sides are paralell
