In this "Math Made Easy" geometry episode, you learn how to prove that two triangles are congruent (equal) by using the "side-side-side" evidence. By using "side-side-side" to prove that two triangles are congruent, you are stating that all the respective corresponding sides of two triangles are equal in length thus proving the triangles are congruent. The narrator in this tutorial provides you with definitions about statements, proofs, and congruency. This becomes useful when setting up a ta...
This video shows the method to prove some trigonometric identities. This involves the use of algebra and knowledge of basic trigonometric identities.

Bastion has several different challenges that are accessible via the proving grounds in the game. If you happen to venture to Zulwood Grove, try your hand at the Scrap Musket challenge after taking a look at this tutorial. It contains information on all the useful upgrades necessary to beat it so that you can walk away with first prize.
The last proving ground in Bastion can be a little tricky. It requires you to use the calamity cannon weapon to stop invading enemies from destroying statues. One little trick to earning first prize in both the XBLA and PC versions of the game is grabbing the 'increased blast radius' upgrade for the cannon.

This is a tutorial about how to prove the congruency (equality) of two triangles when the values of two angles and an included side of each triangle is given. The author of this video instructs the viewer that it should be first determined whether the values of two angles of one triangle are the same as those of two angles of the other triangle. Then one must seek to determine the equality of sides included in those angles in both the triangles. When it is found that these three values in one...

This is a video tutorial on how to prove congruent triangles with SSS and SAS test. SSS means side-side-side and SAS means side-angle-side. For applying the SSS test of congruency, each side of one triangle must be congruent to the corresponding side of the other triangle. For applying the SAS test of congruency, two corresponding sides of the two triangles must be congruent as well as the angle between those two sides of each triangle must be congruent. Follow the rest of the video to unders...
Like a lemon, a potato can produce electricity. This science experiment was prepared by Ebtisam Al Anzoor and demonstrated by Mustafa Daif. The electricity is proven using an analog micro ameter. The positive is copper from a penny or copper coin while the negative is a galavanized nail. The potato releases a charge and is further proven when it is connected to a calculator. You can daisy chain the potatoes for a greater charge.
