Will congruent chords always form isosceles triangles with the center point?

Yes

Step-by-step explanation:

In a circle we have suppose two chords congruent.  Now imagine the two triangles formed by connecting each chord ends to the centre.

These two triangles will have all three sides congruent because

Chord length = equal (given)

Other sides = equal (radii of the same circle)

Thus by SSS axiom these triangle will be congruent to each other and also the triangles formed would be isosceles since radii are equal.

step-by-step explanation:

no of data

divide by no of mode

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
