Someone plz im rlly struggling
in a quadrilateral abcd, the diagonals intersect at point t. thomas has used the alternate interior angles theorem to show that angle adb is congruent to angle dbc and that angle dba is congruent to bdc.

which of the following can thomas use prove that side ab is equal to side dc?

ac ≅ ac
ac ≅ db
ta ≅ tc
db ≅ db

Find the length of the normal and the angle it makes with the positive x-axis. (see pictured below)

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
