GEOMETRY
what is it??
ANGLES
well as you know and probably heard there are four types of angles ACUTE,RIGHT,OBTUSE,AND STRAIGHT. so what do these angles look like? well i´ll show you.
RIGHT ANGLE
it's the right angle to use and it measures 90 degrees
OBTUSE ANGLE
it's big?? and it measures over 90 and less than 180
ACUTE ANGLE
it's so small and cute and it measures under 90 but over 0
PROTRACTOR
what's a protractor you ask? well,it's the tool you use to measure all those types of angles from acute to straight.it's kind of like a ruler in some ways, but the way you use it is you put the little hole in the middle on the vertex, then you line up the end along one ray, measure it and there you go you just used a protractor.
Triangles
there are ,just like angles, different types of triangles like..
RIGHT TRIANGLE
this is a right triangle the little box in the corner means the angle measures 90 degrees.
ISOSCELES TRIANGLE
this is a isosceles triangle, the lines on the side mean that those angles measure the exact same degree.
OBTUSE TRIANGLE
this is a obtuse triangle you can tell because it only has one obtuse angle
there are more than this but i didn´t fit them all the other types are scalene,equilateral,and acute.some of them have the names of angles and that´s because they have those angles in them.
QUADRILATERALS
quadrilaterals are four sided figures. most of the time the angles are all right angles. there are many different types like rectangle,square,polygon,parallelogram,trapezoid,and a rhombus.
SQUARE
this is a square all sides are congruent,opposite sides are parallel,all angles are 90 degrees.
RECTANGLE
this is a rectangle it's the same as a square the angles, the sides a square is a rectangle.
RHOMBUS
this is a rhombus it's a 4 sided polygon,all sides are congruent,opposite angles concruent
FUN WITH GEOMETRY
okay some people ( lots of people ) say they don´t like geometry, well there are fun things to do with it like just look at this.they wrote a song about it.
