What is congruent triangle?

  • Two figures are said to be "congruent" if they can be placed perfectly over one another. Both of the bread slices are the same size and shape when stacked one on top of the other.
  • Congruent refers to having precisely the same form and size.
  • If all three sides of two triangles are the same, they are said to be congruent.
  • If we have a side, an angle between the sides, and then a second side that is congruent, we know they are congruent. In other words, side, angle, side.

ΔONP and ΔUTV are congruent .

Can the exponent in the denominator be subtracted from the exponent in the numerator when the based are different? Explain
erastova [34]

Answer:

If the higher power is in the denominator, put the difference in the denominator and vice versa, this will help avoid negative exponents and a repeat of step 3. Step 6: Raise each coefficient (or number) to the appropriate power and then simplify or reduce any remaining fractions. Step 1: Apply the Zero-Exponent Rule.
