If abcd was a rhombus, and p was the intersection of its diagonals, what must be true?
the diagonals ac and bd are congruent to each other
the diagonals do not bisect each other.
the diagonals are perpendicular to each other.
angle a = angle b

Assume that a population of 50 individuals has the following numbers of genotypes for a gene with two alleles, b and b: bb = 30, bb = 10, and bb = 10. calculate the frequencies of the two alleles in the population’s gene pool.

How many terms does the polynomial x^2 y^2 have

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
