explain how proving two triangles congruent can help prove parts of the triangle congruent will do branliest
AleksAgata [21]

How many facts does it take to make triangles congruent? Only 3 if they are the right three and the parts are  located in the right place.

SAS where 2 sides make up one of the three angles of a triangle. The angle must between the 2 sides.

ASA where the S (side) is common to both the two given angles.

SSS where all three sides of one triangle are the same as all three sides of a second triangle. This one is my favorite. It has no exceptions.

In one very special case, you need only 2 facts, but that case is very special and it really is one of the cases above.

If you are working with a right angle triangle, you can get away with being given the hypotenuse and one of the sides. So you only need 2 facts. It is called the HL theorem. But that is a special case of SSS. The third side can be found from a^2 + b^2 = c^2.

You can also use the two sides making up the right angle but that is a special case of SAS.

Answer

There 6 parts to every triangle: 3 sides and 3 angles. If you show congruency, using any of the 3 facts above, you can conclude that the other 3 parts of the triangle are congruent as well as the three that you have.

Geometry is built on that wonderfully simple premise and it is your introduction to what makes a proof. So it's important that you understand how proving parts of congruent triangles work.

Does it matter what interval you use when you find the rate of change of a proportional relationship
LekaFEV [45]
Proportions are the comparison of two equal ratios. Therefore, proportional relationships are relationships between two equal ratios.  So yes, it does matter.. I<span>nterval: all the numbers between two given numbers.</span>

Find the least common multiple of these two expressions.<br> 10v^6y^7 and 6w^4v^5y^3
egoroff_w [7]

10v⁶y⁷    = <u>2</u> * 5 * <u>vvvvv</u>v * <u>yyy</u>yyyy      

6w⁴v⁵y³ = <u>2</u> * 3 * wwww * <u>vvvvv</u> * <u>yyy</u>

GCF: 2v⁴y³

<em>The LCM is the GCF and everything leftover</em>

LCM: 2v⁴y³ * (5 * v * yyyy) * (3 * wwww)

       = (2 * 5 * 3) * (v⁴ * v) * (w⁴) * (y³ * y⁴)

       =        30           v⁵        w⁴        y⁷

Answer: LCM =  30v⁵w⁴y⁷
