Homework Help Home Homework. I quit my job to do algebra. I quit my day job, in order to work on algebra. My mission is to make homework more fun and educational, and to help people teach others for free. Password reset for absent minded professors I added a function to reset a forgotten password. It asks you for the registered email address, and resets a password if you prove that you own the email address.

Three-dimensional geometry worksheets that are based on connecting cubes and worksheets for classifying three-dimensional figures. Connecting cubes can be a powerful tool for developing spatial sense in students. The first two worksheets below are difficult to do even for adults, but with a little practice, students will be creating structures much more complex than the ones below.
Use isometric grid paper and square graph paper or dot paper to help students create three-dimensional sketches of connecting cubes and side views of structures. This section includes a number of nets that students can use to build the associated 3D solids.
All of the Platonic solids and many of the Archimedean solids are included. A pair of scissors, a little tape and some dexterity are all that are needed. For something a little more substantial, copy or print the nets onto cardstock first.
You may also want to check your print settings to make sure you print in "actual size" rather than fitting to the page, so there is no distortion. Trigonometric ratios are useful in determining the dimensions of right-angled triangles. The SOH part refers to the ratio: The CAH part refers to the ratio: The TOA refers to the ratio: Identifying Regular Shapes from Triangles to Octagons. Plotting coordinate points to make drawings.

Imagine it continuing indefinitely in both directions. We can name a line using two points on it. This is line EF or line note the arrowheads. Or, we can name a line using a lowercase letter: We can name a ray using its starting point and one other point that is on the ray: Or, we can name a ray using a lowercase letter: What is an angle?
Many people think that an angle is some kind of slanted line. But in geometry an angle is made up of two rays that have the same beginning point. To name an angle, we use three points, listing the vertex in the middle. Write if each figure is a line, ray, line segment, or an angle, and name it. Find the angle formed by the rays DE and DF.
How do we name it? Find the angle formed by the rays CA and CE. Draw two points, D and E. Then draw line DE. Draw point Q not on the line. It is called the straight angle. Your two pencils rays are lying down flat or straight on the floor.
In each of these pictures the angle is opened more and more and keeps getting bigger. The arc of the circle is larger. Think of acute angles as sharp angles. If someone stabbed you with the vertex of an acute angle, it would feel sharp.
The angle is opened even more now.

Sines and cosine, angles and formulae. Statistics Here's where we cover basics, like the mean & and median, along with links to more advanced statistics topics. An angle whose measure is 90 degrees is called a right angle. An angle whose measure is less than 90 degree is called an acute angle. An angle whose measure is more than 90 degrees is .
The table below shows the types of angles used in geometry. SchoolTutoring Academy is the premier educational services company for K and college students. We offer tutoring programs for students .
