Drag the tiles to the correct boxes to complete the pairs.
The figure shows AABC with m ABC = 90°.
The first 10 steps to prove that AB + BC2 = AC are given in the table. Match the remaining steps to their correct sequence in the proof.
Statement
Reason
1. Draw BDLAC. construction
2. ABC = 2BDC Angles with the same measure are congruent.
4. BCA2DCB Reflexive Property of Congruence
4. AABC-ABDC AA criterion for similarity
Corresponding sides of similar triangles are proportional.
6.
BC2 = ACⓇ DC
cross multiplication

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

you can't solve x because it is 2 linear equation and you only have one equation
