The diagonals of an isosceles trapezoid are congruent. true or false

True

Step-by-step explanation:

Trapezoid: It is that four sides figure in which one pair of opposite sides is parallel.

Properties of isosceles  trapezoid:

1.The base (bottom and top) of an isosceles trapezoid are parallel

2.The angles on either side of bases are congruent.

3.One pair of opposite sides of isosceles trapezoid are congruent.

4.Diagonals of isosceles trapezoid are congruent.

5.Area of isosceles trapezoid=

Where are opposite parallel side of trapezoid

6.Perimeter of isosceles trapezoid=

The diagonal of an isosceles trapezoid are congruent.

It is true .

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

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.
