how do we find the area of parallelograms,kites, and trapezoids ?
the area o a parallelogram is BxH just like the rectangle
the area of a trapezoid is (b1+b2/2)H.
the area of a kite is d1,d2/2
just plug the numbers as seen on the formula.

the area of a kite is d1,d2/2

how do we calculate the area of rectangles and triangles?
the area of a rectangle is BxH
for example-if the base was 3 and the height was 4, the area would be 12
the area for a triangle is 1/2BxH
for example- if the base was 2 and the height was 7, both the base and the height will equal to 14 . hal of 14 is 7 so thats the area.

How do we use the other definitions of transformationhow do we solve logic problems using conditional ?
Glide reflection-the combination of a reflection in a line and a translation among that line
Orientation-refers to the arrangement of points, relative to one another, after a transformation has occurred
Isometry-is a transformation of the plane that preserves length.
Direct isometry- both the length (the orientation) is the same.
Opposite isometry- changes the order
Invarianti- figure or property that remains unchanged under transformation of the plane is referred to as invariant no variations have occurred.

conditional- if 2 angles are congruent , then the 2 ares are not right angles.

What is a mathematical statement?
A mathematical statement is a statement that can state without or not its true or false
For example:
1. 5 is more than 3
This statement is true because 5 is bigger than 3
2. Is a square a rhombus?
this is not a mathematical statement, its just a question
