Two right triangles that are not similar still may have one congruent acute angle in common. a. true b. false

B.False

Step-by-step explanation:

We are given that two right angle are not similar and they have one congruent acute angle in common.

We have to tell the statement is false or true.

Suppose two right angles triangle ABC and EFG which are not similar

Let Angle B and angle F are of 90 degrees

One acute angle common in two triangles

Suppose that angle C=angle G=x, angle A=y, angle E=z

In right angled triangle ABC

In right  angled triangle EFG

Substitute the values equal then we get

Hence, all three angles of a right triangle are similar to all three corresponding  angles of another right angled triangle.

Therefore, the two triangles must be  similar by AAA similarity postulates.

Hence, the statement is false.

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.
