SHAPES, ANGELS, AND DEGREES EVERYWHERE
There are 4 different types of angles. One , is acute angles, which is less than 90 degrees. The next angle is Right angle, which measures exactly 90 degrees . Another angle is Obtuse angle , which is more than 90 degrees. The last angle is Straight angle , which measures exactly 180 degrees
First triangle is Acute triangle, which has 3 acute triangles. The second triangle Scalene, which has 0 congruent sides and 0 congruent angles. The third triangle is Right, which has 1 right angle and 2 acute angles. The fourth triangle is Isosceles triangle, which has 2 congruent sides and 2 congruent angles. The fifth triangle is Obtuse , which has 1 obtuse angle and 2 acute angles. Last but not least is Equilateral triangle, which has 3 congruent sides and angles.
Not So Quiet Quadrilaterals
First is the Rectangle. Opposite sides are parallel. All angles are right 90 degrees angles. opposite sides are congruent. Second is Parallelogram which,opposite sides are congruent. Opposite angles are congruent. Opposite sides are parallel. Third is Square. All angles are right 90 degree angles, opposite sides are parallel, and all sides are congruent. ( A square is a special rectangle and a special rhombus. Fourth is Rhombus which, has opposite sides are parallel, all sides are congruent,and opposite angles are congruent. Last but not least is Trapezoid which has, exaclty one pair of parallel lines
First of all, a quadrilateral angles equal 360 when you add them all together. A triangle equals 180 no matter what. To get the answer for quadrilateral you add all of the numbers it gives you and then you subtract it by 360. For Triangles you add all the numbers it gives you and then you subtract that by 180.
