### Plane Geometry

2007-11-22 00:00:00

Roughly 20 percent of the questions on the Math IC test cover plane geometry. In addition, questions that deal more specifically with s...

### Lines and Angles

2007-11-22 00:00:00

A line is a collection of points that extends without limit in a straight formation. A line can be named by a single letter, like line ...

### Polygons

2007-11-22 00:00:00

Polygons are enclosed geometric shapes that cannot have fewer than three sides. As this definition suggests, triangles are actually a t...

### Circles

2007-11-22 00:00:00

Circles are another popular plane-geometry test topic. Unlike polygons, all circles are the same shape and vary only in size. Circles h...

### Key Formulas of Plane Geometry

2007-11-22 00:00:00

Pythagorean Theorema2 + b2 = c2, where a and b are the lengths of the legs of a right triangle, and c is the length of the hypotenuse. ...

### Solid Geometry

2007-11-29 00:00:00

Solid geometry adds literally another dimension to the plane geometry explained in the previous chapter—instead of squares and circles...

### Prisms

2007-11-29 00:00:00

Most of the solids you’ll see on the Math IC test are prisms, or variations on prisms. A prism is defined as a geometric solid with tw...

### Solids That Aren’t Prisms

2007-11-29 00:00:00

Some of the solids that appear on the Math IC do not have two congruent bases that lie in parallel planes, so they cannot be considered...

### Relating Length, Surface Area, and Volume

2007-11-29 00:00:00

The Math IC tests not only whether you’ve memorized the formulas for the different geometric solids, but also whether you understand t...

### Inscribed Solids

2007-11-29 00:00:00

An inscribed solid is a solid placed inside another solid, with the edges of the two solids touching. The figures below are, from left ...

### Solids Produced by Rotating Polygons

2007-11-29 00:00:00

Another type of Math IC question that you may come across involves a solid produced by the rotation of a polygon. The best way to expla...

### Key Formulas of Solid Geometry

2007-11-29 00:00:00

Length of a Diagonal of a Cubed = = s where s is the length of one edge of the cube. Length of a Diagonal of a Rectangular Solidd ...

### Coordinate Geometry

2007-12-19 00:00:00

Coordinate geometry questions make up about 10 percent of the Math IC test. Many of the basic concepts in this chapter may be familiar ...

### The Coordinate Plane

2007-12-19 00:00:00

The coordinate plane is a plane determined by two perpendicular lines, the x-axis and the y-axis. The x-axis is the horizontal axis, an...

### Lines and Distance

2007-12-19 00:00:00

Lines and distance are fundamental to coordinate geometry, not to mention to the Math IC test. Even the most complicated coordinate geo...

### Lines

2007-12-19 00:00:00

Lines are nothing more than an infinite set of points arrayed in a straight formation, but there are a number of ways to analyze them. ...

### Graphing Linear Inequalities

2007-12-19 00:00:00

The graph of an inequality is a graph of a region rather than a simple graph of a line. An inequality is actually the graph of all the ...

### Other Important Graphs and Equations

2007-12-19 00:00:00

In addition to the graphs and equations of lines, the Math IC will test your understanding of the graphs and equations of parabolas and...

### Coordinate Space

2007-12-19 00:00:00

When we add another dimension to the coordinate plane, creating a coordinate space, a new axis must be introduced. Meet the z-axis: ...
