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

How do we solve problems using reflections?
You can solve problems using reflections by graphing and labeling the coordinates. For example, you could use graphing paper to help and it could say sketch coordinates A(1,1), B(0,4) & C(5,-1). Graph the points on the graph paper. it then saids to graph its reflection in the line x=1. On the graph paper draw a line across the 1 on the x-axis. count front the point to the line and theres your new point to plot. when your done, connect the points and there you have created your reflection.
