ACT Math: Plane Geometry Drill 4, Problem 1. What is the radius of the sphere?

ACT Math: Plane Geometry Drill 5, Problem 5. How much material do you need to cover the entire tent?

Measurement and Geometry Drill 4 Problem 1. What is the total volume of the figure?

FYI: cats don't like to get wet. Okay, so that fact won't be relevant every time you solve trig equations, but it happens to be this time.

We inscribed some angles on the walls of our office, but our boss got mad, so we made this video instead.

Unlike anything that enters the Bermuda Triangle, Exterior angles can be found—in more than one way. This video covers how to use the remote inte...

Los cubos de hielo no son ruidosos generalmente...pero tienen un volumen de tipo diferente. Este video te enseñará cómo encontrar el volumen de...

Volume is crucial to our lives. It determines the amount of food we eat, the amount of fluid we drink, and hydraulics, just to to name a few. One o...

SAT Math 1.4 Geometry and Measurement. If the sides of a square increase in size by 25%, what happens to the area of the square?

This video can run circles around other videos about circles. Sir Cumference, of Round Table fame, explains all the properties of… well, circles....

Time to learn about the area of a sector. And no, that's not the sector's bedroom with a bumper sticker on the door that reads, "GO AWAY."

Equations of circles are a no-brainer. If aliens can do it, so can you. All you do is substitute the center of the circle's coordinates into the eq...

ACT Math: Plane Geometry Drill 5, Problem 3. What is the measure of Angle GHJ?

To prove lines are parallel, you need a third line. We at Shmoop (and the rest of the world) call it a transversal.

ACT Math: Coordinate Geometry Drill 5, Problem 2. Which of these three lines are parallel?

Who knew triangles had midsegments? We did.

Talk about math being applicable to real life.

One formula to rule them all, one formula to find them. One formula to bring them all, and in the darkness bind them. Or something like that. I...

CAHSEE Math Mathematical Reasoning: Drill 2, Problem 5. Which of the following conclusions can be drawn based on the above information?

Mathematical Reasoning Drill 5, Problem 1. Which of the following could be the number of pieces the lasagna was cut into?

Mathematical Reasoning Drill 5 Problem 3. Which of the following could be the integer mentioned?

This video explores parallel lines and transversals: how to identify them both on a math test and in real life urban planning. What do the consecut...

Prove it, Shmoopers. We dare you.

To prove lines are parallel, you need a third line. We at Shmoop (and the rest of the world) call it a transversal.

SAT Math 4.3 Geometry and Measurement

It's super useful to be able to find the distance around stuff. Like when you’re being pursued by authorities while running around the base of an...

ACT Math: Plane Geometry Drill 2, Problem 1. What is the perimeter of the shape shown?

Rhombi are a girl's best friend. Or so we've heard, anyway.

Rectangles just love to have perimeters. And we just love to measure them.

SAT Math 4.1 Geometry and Measurement

Verifying trig identities is important, especially when you're about to let one of them into the country—which is why they should keep their pass...

Mosquitos need their caffeine, just like the rest of us. Wouldn't think zipping around and stinging people all day long sap your energy?

ACT Math Trigonometry Drill 1, Problem 2. Can you find the tangent?

Bien, tú no eres el único que cae completamente en el aburrimiento por un rato. Dos figuras geométricas dimensionales también. ¿Cómo ellos pu...

SAT Math 11.2 Geometry and Measurement

If you were looking for the trailer for the new Michael Bay movie, you've got the wrong number. Transformations are rotations, reflections, and tra...

Sine is the opposite over the hypotenuse; cosine is the adjacent over the hypotenuse; and tangent is the opposite side over the adjacent side....

Someday you might be a big, fancy defense lawyer, and you'll have to prove that your client's triangle was congruent to the triangle in question. W...

SAT Math 2.3 Geometry and Measurement. Find the length of AB.

Measurement and Geometry Drill 5 Problem 1. A parcel of land measuring 64 square kilometers is equivalent to an area of how many square miles?

We’ve got a problem. Actually, we’ve got a ton of them. Fortunately, they’re only geometric word problems, which really aren’t so bad. Weâ€...

How do you figure out how long you have before the Galapagos Zombie Tortoises eat you? By using math, of course. If you can't solve this problem, w...
