<u>Congruency</u> property relates to two or more <em>triangles</em> with similar <em>dimensions</em>, and internal<u> angles</u>. So that the required <u>statements</u> to complete the proof are:

1. <em>definition</em> of a <u>straight</u> angle.

2. <u>subtraction</u> property of equality

3. <em>corresponding</em> sides of <u>similar</u> triangles are <u>proportional</u>

4.<u> transitive</u> property of <em>equality</em>.

The <u>intersection</u> of two or more lines forms a number of <em>angles</em> which depends on the <u>number</u> of lines involved. These <u>angles</u> formed may have <em>similar</em> or<em> different </em>properties.

When two or more <u>triangles</u> have <em>similar</em> lengths of <u>sides</u> and measure internal <u>angles</u>, it can be said that they are congruent. Thus they have some <u>common</u> properties.

Therefore, the appropriate <u>statements</u> to answer the given <em>question </em>are stated below:

  • <em>Definition</em> of a <u>straight</u> angle.
  • <u>Subtraction</u> property of equality.
  • <em>Corresponding</em> sides of <u>similar</u> triangles are <u>proportional.</u>
  • <u>Transitive</u> property of <em>equality</em>.

Help !!<br>I can't understand it <br>​
siniylev [52]

1.

a.) The color of <u>Aqueous solution</u> turns <u>light green</u> from <u>blue</u>, due to formation of <u>iron sulphate</u> .

b.) The color of the <u>Aqueous solution</u> turns <u>colorless</u> from <u>blue</u> due to formation of <u>zinc sulphate</u>.

2. <u>Bells</u> used in temples aren't made up of wood because wood isn't <u>sonorous</u> and hence can't produce <u>ringing sound</u>, and hence metals are used in making bells.

3. <u>phosphorous</u> is kept in water because it is <u>highly reactive</u> and reacts vigorously with air if left free in atmosphere .

4.

a.) CuSO4 + Mg =》MgSO4 + Cu

this is a <u>single displacement reaction</u>, where <u>Magnesium</u> being more reactive than <u>Copper</u>, displaces copper from its compound (copper sulphate) to form <u>magnesium sulphate</u>.

b. H2SO4 + Zn =》ZnSO4 + H2

this is a <u>single displacement</u><u> </u><u>reaction</u>,

where <u>Zinc</u> being more reactive than

<u>hydrogen</u>, displaces hydrogen from its

compound (sulphuric acid) to form <u>Zinc</u><u> </u><u>sulphate</u>.
