A congruence theorem for two right angled triangles |
2016-07-17 |
|
From Sayari:
Hello.
Is it possible for two right angled triangles to have the same length of base and height and a different hypotenuse? If not so, then why in the congruence criteria RHS the hypotenuse is given more importance? It can also be like- 'two triangles are congruent if they are right angled and have the same base and height.'
Thank You.

From Andrew:
If n.q == k mod (m) (where n, q, k, m, are integers & q is a prime)
Is it true that 'k' is always divisible by q?

From Sherry:
1. If Circle K has tangents RT and TY where R and Y are the points of tangency, then angle RKY and angle RTY are supplementary.
2. If one diagonal bisects a pair of opposite angles in a quadrilateral, then the quadrilateral is a kite.

Manufactures golf balls |
2001-11-06 |

From Kevin:
A company manufactures golf balls. Golf balls are each numbered consecutively 0 to 4, and then the numbering starts over with zero again. Every 12th golf ball is yellow. Every 8th golf ball is tested for defects. The company produces 120,000 golf balls in an eight-hour shift. A. How many yellow golf balls are tested for defects during the day? Explain your reasoning. B. How many of these yellow balls that are tested are imprinted with the numeral 2? Explain your reasoning.

Congruence and symmetry |
2001-02-21 |
|
From Chris:
My name is Chris and I am a second-grade teacher. I would like to know what the difference is between congruent and symmetry, and how do I explain this to my class? I know that congruent means the same, and symmetry is two identical sides. Is there a difference between the two? I know there must be, but I don't know what or how to explain these two terms.
