In a parallelogram, two points on the parallel sides are joined to vertices. The task is to prove that the resulting quadrilateral is a parallelogram

In the parallelogram ABCD, AN bisects the angle DAB, NC bisects angle BCD. Prove that AMCN is a parallelogram.

Graph and simultaneous equations

Accurately and neatly graph and label each of the equations and estimate the point of intersection of the two lines. Mathematically solve for the exact point of intersection of your two lines compare your mathematical solution with your graphical solution. Similar? Why? Not similar? Why or why not x + 2y = 14 4x - 2y = 18

can you lease check my work

I have attached a file regarding contrapositives and inverse and converse statements --- Statement: If two lines are parallel then they do not intersect. True Converse: If 2 lines do not intersect then they are parallel False Inverse: If 2 lines are not parallel then they intersect False Contrapositive: If 2 lines do intersect then they are not parallel True Statement: If measure of angle A is not 90 then angle A is not a right angle True Converse: If angle A is not a right angle then it doesn't = 90 False Inverse: If measure of angle A isn't 90 then angle... click for more

The measure of each interior angle of a regular polygon...

The measure of each interior angle of a regular polygon is 11 times that of the exterior. How many sides does the polygon have? I think that each interior angle would equal 165 degrees and each exterior angle would equal 15 degrees. But I dont know the formula to figure out the number of sides it has.

I working on college algebra we are doing geometry

Geometry has many practical applications in everyday life. Estimating heights of objects, finding distances, and calculating areas and volumes are commonplace. One of the most fundamental theorems in geometry, the Pythagorean Theorem, allows us to make many of these calculations. The Pythagorean Theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides, as shown in the diagram below. The problems in this Unit will give you an opportunity to practice these applications. Solve the following problems and submit them in a Word document. 1.
